Suspecting:r409143?

Kindly help to re-assign if your change is not the cause for this issue.

Adding release block label, please undo if not the case.

Yup, this is definitely caused by my change, and should be a beta blocker. Investigating now.

This is really tough to diagnose... Clearly there is a recalc call missing somewhere, but finding it is difficult.

The only things I can see that are unique about this page is that it uses visibility: inherit (which may have strange behavior, but none that I can repro locally), and has 2 shadow roots that independent inherited changes to visibility propagate through, although the bug isn't fixed by crrev.com/2212223002.

The only way I can get this to work by disabling the fast-path entirely.

Rune@/esprehn@, any ideas? Attached a somewhat minimized test case... It's hard  to further minimize because the page uses some kind of library, awmlib2.js, which is minified and does all kinds of crazy things.

This is dev blocker, you caused two regressions by touching something core to the style engine. That means a the real breakage is possibly much worse. Please revert while we understand what happened. :)

Leaving canary in an unknown broken state for days is bad.

Minimal test.

I've triggered a revert from the CL.

The generated applyInherit... methods sets setIsInherited to false instead of true.

Removing the RB-Beta as per # 6

FYI: Thee revert was landed in https://chromium.googlesource.com/chromium/src/+/bf9f7aeb812949577490b55e40dd36c8eca7b8f9

This is working fine on current canary build 54.0.2823.0 - Win7/64 bit, Mac OSX 10.11.5 & Linux/Ubuntu 14.04

Can you please mark this bug as Fixed ?

Rechecked this on chrome version 54.0.2824.0 on Windows 7 and MAC 10.11.6, 54.0.2823.0 on Ubuntu 14.04. Fix is working as intended. Header links are properly displayed. Adding TE-Verified labels.

Thanks.!
