@ryansturm: Could you please check whether this is caused with respect to your change, if not please help us in assigning it to the right owner.

Note:
1.Unable to provide 'per-revision' bisect as it shows "We don't have enough builds to bisect" error message.
2.Tried on other machines but still getting the same error again.
3.Above issue is Touch specific and not seen on Win(7,8,8.1,10),Mac(10.13.1 , 10.13.6 , 10.14.2)  and Linux(14.04 LTS)

Tbansal, this seems very unlikely to be caused by the listed CL, since they would only affect Android with previews and shouldn't affect UI like this. Can you look a little more at this to triage it to someone else?

I do not think it's because of the CL suspected in #0 above.

Looking at the bisect range (https://chromium.googlesource.com/chromium/src/+log/72.0.3597.0..72.0.3599.0?pretty=fuller&n=10000), it seems there were few CLs that seem to change the tab-strip code. 

https://chromium-review.googlesource.com/c/chromium/src/+/1249461 is also  suspicious. Adding related folks (sangwoo108, erikchen, sky) to get more expert opinion.

From the bisect range, https://chromium-review.googlesource.com/c/chromium/src/+/1300676 also seems suspicious.

Comment 5 by anowlcal...@gmail.com, Nov 10 

This isn't touch-specific – it also happens on 72.0.3602.2, Ubuntu 18.04, when using either keyboard or mouse. However, it only happens when the newly-selected tab is to the right of the currently-selected tab (i.e. with two tabs open, it only occurs when you select and close the leftmost tab).
