Fix #279 - Use getBoundingClientRect for proper scaled width of slider

Jcqt-390's solution also worked for me:
#279

I see now that this gives failing tests. Will take a look.

I've cherry-picked your commit into a separate pull request which also resolves the failing tests. #293

@dbryand could you fix the CI and add a unit test for this?

[benjycui]

add a unit test for this?

Oops.. it seems that it is hard to add unit test for this. But please fix CI at least.

[dbryand]

Will give it a shot when back to work in a few days.
