using cosesearch, seeing some changes to 'TextIterator.cpp' in https://chromium.googlesource.com/chromium/src/+/3564239b151f615afca39cfd886d225a2b4740f8

joone.hur@intel.com - Could you please check the above issue & help us in finding an owner it its not yours.

Is DOM tree modified in InPreLayout or AfterPerformLayout?

It seems to be an issue of |updateStyleAndLayoutIgnorePendingStylesheets|.

In the crash site, |createPlainText| already calls |updateStyleAndLayoutIgnorePendingStylesheets|, but immediately after that, the DCHECK is hit in TextIterator's constructor saying that layout still needs update.

Triage to some other component?

Triaging to CSS team according to #4.
