WP Admin Menus/SubMenus Overlap in small screen

[turtlepod]

Hello,

did anyone know about this/ever experience this issue with wp-admin?
or maybe this is a known issue?

If wp-admin is displayed in browser with "short" height (not only narrow), when we open a sub menu, it will overlap (and practically go crazy all around).

here’s the screenshot in:
desktop (resized) firefox + chrome (latest version, win7)

windows tablet( hp stream 7 ), using firefox (latest, win 8.1 with bing)

I can’t reproduce it in android/other mobile, because i can't resize the screen/browser size.

tested with latest wp (4.2.2) clean install. no plugin activated, tested with default theme too.

how to reproduce this issue.

1. resize the browser to be as short/small as in the screenshot.
2. visit wp-admin
3. click hamburger icon in admin bar to reveal admin menus
4. click parent menus such as "appearance" menu to view the sub menus.

note:
if i make the browser taller, the menus works fine.

maybe because wp_is_mobile() ?
(since ff browser in windows tablet is detected as desktop browser (it's a full version of windows) and not touch screen, maybe that's why it's working fine on my android phone.

thanks.
David.

i change the user agent in firefox to:

Mozilla/5.0 (Android; Mobile; Touch; rv:22.0) Gecko/22.0 Firefox/22.0

and the problem is gone.
the menus is working fine.

this will make wordpress detect the browser as mobile and touch browser(?)

so i believe the problem happen because of screen size and browser type (wp is mobile / user agent detection) conflict in wp admin design.

Your issue is actually #33199, see also a ​WP Tavern post for details and a workaround.

Thinking this should be investigated testing with real mobile devices. Going to remove the "accessibility" focus since it's more a general issue not specifically tied to accessibility.
