This would have nothing to do with my change. I'm adding Blink>Editing>Selection because they might be able to help with the text bounds of the find in page it seems incorrect.

drott@, could you take look?

It seems this is font metrics issue in Android. One or two pixels of vertical bar 
at top overshoot marker and selection background painting.

I attached screenshot of windows. There are no overshoot for character "이".

Not reproducible on Nexus 7 with Chrome Beta 62.0.3202.29. See attached picture.

ramya.v@, on which phone is this? Could you connect the phone in developer mode via USB, on desktop Chrome, go to chrome://inspect and run DevTools on the site, then inspect the element containing the FAQ answer, and look at the bottom of the Computed Style pane to see which font is used? (Compare my screenshot).

On the Nexus 7, NanumSquare is used and the selection looks okay. Perhaps this is issue with the font?

Sorry, NanumSquare is a web font, so it should be the same font, independent of device model. I'll try with Chrome stable and Canary.

Sorry (2): The device I was using was not a Nexus 7, but a Nexus 6 phone. 

Not reproducible on Chrome 61.0.3163.98 stable on Android on Nexus 6.

If I remove the NanumSquare font-family CSS, the text gets rendered in Noto Sans CJK SC Regular and Roboto, and the selection still paints okay in 61.0.3163.98 stable.

Hi issue is on Galaxy Note 8 device, and issue is not with selection rect, it is painted correctly. Issue is with when we copy selected text and find in page the same text, find in page result rect is overlapping with text.
