[OPEN] [#1576] [4.5.1] Strange behavior of dropdown in popup
Hello
I'm not sure if you will be able to reproduce this as behavior depends on resolution
the button displays the window. Window is displaied fine, but once I expand the dropdown, thr dropdown disappears
it looks like the window is displayed on top of screen and dropdown expand on the bottom (see attachments)
reproducible in all 3 major browsers, I have 1900x1200 resolution
As well it's reproduced only if user start on the top of the page, scroll down and click button. If user start on the bottom ( after page reload for example) it works fine. Our use case is that users have long page to read so has to scroll couple pages and on the bottom has some buttons to click.
