User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.111 Safari/537.36

Steps to reproduce:

I have a bootstrap slider in my website and when the slider is sliding while my select dropdown is open, the dropdown disappears.


Actual results:

It seems like the changes in the style attribute of an HTML-element to animate the element, triggers the select to hide the options.


Expected results:

The dropdown should stay open, the options should keep being visible during the animation.

Could you attach a minimal testcase, please.

You can see the website running on http://otto.yndenz.com/. When you hover the menu item "occasions" in the header you see the dropdowns. Click the dropdown to show the options and wait for the slider to slide.

If you want a code snippet I can work on that but it takes some time ;)

OK, I see the issue. I thought it was in FF44 by default due to your Firefox UA missing but Nightly (FF47) is broken.
It's a regression, I'll find a regression range.

Reporter, what's your Firefox UA?

My UA is Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:38.0) Gecko/20100101 Firefox/38.0

I think it has been patched after FF38 (at least partially).

Could you test with these versions and report your results, please:

1) current release 44: https://www.mozilla.org/en-US/firefox/all/

2) nightly 47: https://nightly.mozilla.org/
(both with e10s enabled and disabled "Options > General > Enable multi-process Nightly")

NB: for e10s, only with FF47, sorry.

I'm on 44.0.1 now and the issue doesn't occur. Thanks for the great help and fast replies!

Ty for testing. If you are on ESR, the next one will be ESR 45.

There is still a remaining bug with e10s enabled, but I'll file a new bug. ;)
