.caret rendering problem in Firefox

[bangive]

Link for demonstrating problem: http://jsbin.com/wifike/2/edit?html,css,output
This happend in Firefox 38.0.5 on Windows 7.
The border-top css value of caret in dropdown.less is "dashed" so it is displayed wrong in firefox. When i change the value to "solid" it is displayed right.

This was changed to dashed due to #15682 — I personally feel though that incorrect rendering is worse than the size being off in some cases.

@bangive I can't reproduce this in Win 7 Firefox 38.0.5 on Sauce Labs:

Can you post your original example with the UK flag?

I can't see it on 38.1

@cvrebert you use the same windows 7 and firefox 38.0.5 like me. But why i get error and you are not.
This is the original code that has caret rendering problem http://jsbin.com/yesuvu/2/edit?html,output
The flag does not show because i don't include svg file. If you want i will include svg file.

@kkirsche You didn't attempt to reproduce this, right?

[cvrebert]

Still can't reproduce the problem, even with the new JS Bin:

and even after zooming in:

So, going to close this until/unless someone manages to repro it.

@cvrebert tried but wasn't able to. Must have gotten distracted and forgot to post that. Sorry about that!
