We parse when assigning using the namespaces of the stylesheet. It isn't
clear if the spec says to do that (Firefox doesn't support the setter at
all, Chrome does, Safari doesn't); the spec issue is here:
https://github.com/w3c/csswg-drafts/issues/1511
Also fix ToCss implementation of AttrSelectorOperator to not pad with
spaces, to conform with CSSOM. This means we have to update some unit
tests that expect operators with spaces around them in attribute
selectors to roundtrip.
See the "attribute selector" section of "Serializing Selectors" here:
https://drafts.csswg.org/cssom/#serializing-selectors
CSSStyleRule.selectorText is specified here:
https://drafts.csswg.org/cssom/#dom-cssstylerule-selectortext
Custom element creation
<!-- Please describe your changes on the following line: -->
This implements the CE-related steps when creating elements. `is` is now support by `document.createElement` and is stored on `Element`s. Only synchronously created autonomous elements are supported as async element creation and customized built-in elements both require custom element upgrade reactions.
Spec: https://dom.spec.whatwg.org/#concept-create-element

Fix several bugs related to scrolling
* scrollLeft/scrollTop returned values of parent or even document root
Only the scroll of the node itself is returned. Otherwise 0.0.
* Scrolling via script had set viewport.
This resulted in other nodes appearing scrolled.
Now scroll_offsets are updated with correct node id.
These bugs caused other odd behavior like both body and
document.documentElement being scrolled or the view for scrolled
elements jumping.
Also try scrolling this [example page](https://pyfisch.org/stuff/scrolltest.html) in servo with and without this change.

We already call Document::invalidate_style_sheets and set
the stylesheet member to a new Stylesheet. This matches the behavior of
Firefox, and means the new CSSStyleSheet you get from accessing .sheet
from JS will be correct instead of stale.
(::get_cssom_stylesheet already tries to use the new Stylesheet, but
MutNullableJS::or_init is called, so if we already created a
CSSStyleSheet we will continue to return that one).
Correctly test CSSStyleRule.style.

Remove the assert_readonly test and add one to verify that assigning to
CSSStyleRule.style correctly forwards to CSSStyleRule.style.cssText.
We currently test for whether CSSStyleRule.style is read-only by
trying to assign to it; however, the spec has it as actually:
interface CSSStyleRule : CSSRule {
...
[SameObject, PutForwards=cssText] readonly attribute CSSStyleDeclaration style;
};
See: https://drafts.csswg.org/cssom/
The `PutForwards=cssText` means that assigning to CSSStyleRule.style
should actually assign to style.cssText.
Fix#6799: set stacking_context_position correctly on fragment_border_iterator
Hey,
First of all, this is my first PR to Servo project and I'm learning Rust, so sorry if you see something that it's not correct. I did that as best as I know.
This PR fix the issue #6799; I tried all the corner cases that I can think about it and always get the right result and the same as other browsers.
Related to the build:
- [x] `./mach build -d` does not report any errors
- [x] `./mach test-tidy` does not report any errors
- [x] These changes fix#6799
In the other hand, I added the test in the cssom folder, is where getBoundingClientRect is defined, so I think that is the best place.
I'm sure that the line 122 can be better, but I didn't find a way to transform a Point2D from f32 to px in a easy way.
I'm here to listen to your recommendations and fix any issue.
Thanks!
