… rather than the start location of the current construct.
This likely places the error just *after* of the unexpected token
whereas before would be best, but that’s likely a much bigger change.

style: Optimize custom properties cycle removal.
After #18791, this is the major custom_properties perf bottleneck in the
testcase from bug 1405411.
I'm looking into how to efficiently merge this into `substitute_all`, but
meanwhile this is worth landing, and makes most of the overhead go away.

Use defualt Debug trait for AnimationValue
We use AnimationValue for animation backend to do interpolation,
accumulation, or computing distance. While debugging it, dumping the
property name is not enough. We need to dump the detailed value contained
in it.
For example:
if we animate ```translate(100px)``` to ```translate(200px)```,
and want to dump ```{:?} => {:?}```, the result is ```transform => transform```.
I think what we want is something like:
```Transform([Translate(100px, 0px, 0px)]) => Transform([Translate(200px, 0px, 0px)])```.
Using default Debug trait is not perfect because there are some redundant type strings,
but it is still better than nothing.
