    <thetext>Hi Team,

Came across another potential merge.

Blink Commit - https://chromium.googlesource.com/chromium/src.git/+/047653201597a4e5c3912d8c2c35adaa2ed6e6ec

^ Most stuff in XPathFunctions.cpp.

It might be difficult for me to merge, appreciate if someone else can take it.

Thanks!</thetext>

    <thetext>It&apos;s super weird that this came with a unit test instead of an HTML based one. Is there actually an observable difference?</thetext>
