Don't add empty rects during addFocusRingRects in RenderInline

• Status: RESOLVED FIXED

Hi Team,

While going through Blink's commit, I came across another failing test case in Safari 16.2 & STP160:

Test Case - https://jsfiddle.net/1gvyf5er/1/show

^ Chrome Canary 111 does not show extra focus outline to small rectangle and similar is case with Firefox Nightly 110.

Blink Commit - https://chromium.googlesource.com/chromium/blink/+/2cf30f0fb85c90f6ae813264aa0d0dcc9a85ab58

WebKit Source - https://searchfox.org/wubkat/source/Source/WebCore/rendering/RenderInline.cpp#912

Just wanted to raise since I was not able to find current bug for this.

Thanks!

I manage to do merge and compile this but I think Line 930 is problematic since it does not fix the failing test case, which I have attached here on local build.

Just wanted to share what works so if anyone can highlight mistake, I can fix it or if they can fix it, they can take it up.

Seems like a good merge.

WebKit has addRect() and not operator(). just replace it and it will start working.

Worked!!! (Test case also fixed - test in Minibrowser). Going to draft PR first and once I will fix all bugs, I will do ask for review. :-)
