I suspect this is WONTFIX per bug #1387618 comment 10 & comment 15,
but maybe only button border area should be bigger, not "X" icon if it's too much trouble to tune it.

@  Dão Gottwald [::dao] - What do you think about this?

I verified the issue on Windows 8.1 x64 and it's also reproducible.

This is reproducible on Windows 10 with latest Nightly 57.0a1 using tablet mode - touch density, build ID 20170913220121 as follows:
 - the x button from tab is 20x20px instead of 32x32px
 - the + button next to opened tabs is 33x33px instead of 36x36px

As mentioned in bug 1387618 comment 10, this is currently expected. The button size looks the same as with normal UI density, but the interactive region is actually larger.

Marking P5 for now, but this might be wontfix.
