Text unselection fails on non-integer-scaled Chrome when clicking inside a paragraph

Reported by ivan@ludios.org, Dec 3 2016

Issue description

UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.75 Safari/537.36

Example URL:
http://manishearth.github.io/blog/2016/12/02/reflections-on-rusting-trust/

Steps to reproduce the problem:
1. Start Chrome 55 on Linux with a non-integer scaling factor (e.g. 1.5 instead of 1 or 2) - either through DPI settings or --force-device-scale-factor=
2. Visit any page with a paragraph: http://manishearth.github.io/blog/2016/12/02/reflections-on-rusting-trust/
3. Text-select a paragraph
4. Click *inside* the paragraph to unselect
5. Observe that this fails at least half of the time

Repeat at 1.0 or 2.0 scaling and find that this works a lot more of the time.

What is the expected behavior?
Text is unselected when clicking inside selection

What went wrong?
Text was not unselected

Does it occur on multiple sites: Yes

Is it a problem with a plugin? No 

Did this work before? Yes 54

Does this work in other browsers? Yes

Chrome version: 55.0.2883.75  Channel: stable
OS Version: xbuntu 16.04.1
Flash Version: none

Possibly related to another unselection bug https://bugs.chromium.org/p/chromium/issues/detail?id=670253 but that one says it doesn't affect Linux

Bug title should be s/inside a paragraph/inside the selection/

This also reproduces on this page, which uses a <pre>

Tested on Ubuntu 14.04 using chrome stable M55 #55.0.2883.75 and issue is not reproduced.

Attached screencast for reference.

@MTV Team -- Could anyone from MTV team look into this , as inhouse team doesn't have the xbuntu 16.04.1 .

Thanks!

I just want to mention that "Observe that this fails at least half of the time" seems to be deterministic - clicking on some pixels on the grid causes unselection, while other pixels do not.

Issue is similar to 670253. Hence duping it
