Auto merge of #10246 - mbrubeck:strip-leading, r=pcwalton

Restore stripped whitespace before reflowing text fragments

Fixes #10200. r? @pcwalton

Note: The reftest uses a transition of non-zero duration, because I couldn't find any other way to reproduce the bug.  Unfortunately this makes it unreliable in debug builds. I tried to fix this using reftest-wait with setTimeout and requestAnimationFrame, but it still wouldn't complete the animation consistently.  To make the test work in debug builds we may need `transitionend` events (#10245) or a different way to reproduce the bug.
