Bug 126195 – Lift integer restriction on border-image-width and border-image-outset

• Component: CSS
• Status: RESOLVED CONFIGURATION CHANGED

[Ryosuke Niwa]

Consider merging https://chromium.googlesource.com/chromium/blink/+/69945681720a72bd94a1cb34b3e30d1851aa08a0

border-image-{width,outset} should accept percentages, lengths,
numbers, and auto. A number represents a multiple of the computed
border-width, and should not be restricted to integral values.

I think at least in STP 151 both issues are fixed now. Should we keep it open or this can be considered fix? Thanks!

Drawing red before the subresource png loads wouldn't be part of this issue, so marking resolved.
