Add delay to admin menu arrow's disappearance

[pathartl]

Currently if you hover over an item in the admin's left sidebar, the submenu will show after a few hundred milliseconds. The arrow/triangle next to the submenu will appear at the exact same time. However, on leaving the hover state, the arrow disappears right away while the submenu will stay around for a few hundred milliseconds and then disappear.

I would assume this is because the arrow is bound to the menu item, and not the submenu. Not really sure what the solution would be to this, but I see it as a bug in code that's improves UX.

Changing active submenu arrow to appear based on parent menu class rather than hover state

[afercia]

Please consider any change here should also take into account the focus style and the alternate color schemes in the Sass files.

Update arrow for for other admin color settings including RTL display

[coreymcollins]

Thanks for the mindful eye, @afercia! Here's an example using the Sunrise color scheme in both LTR and RTL displays.

HI @coreymcollins. I'm unable to apply this patch for testing purposes. Would you mind checking if it can be applied?

I'm using grunt patch command on Varying Vagrant Vagrants.

[coreymcollins]

@dwainm This is working fine for me. I applied 34088.1.diff to my branch in Cornerstone and was able to see the changes reflected. I'm not a VVV user, so I can't verify what may be going on there.

Would love for some others to test this as well to see if there may be something funky going on. Thanks!

I tried applying the patch and got errors.

For each CSS line update I get the error

error: css/admin-menu-rtl.css: No such file or directory

The problem is the format of the patch file, it seems.

The file paths in patch 34088.1 start wp-admin...

When they should start /src/wp-admin...

I updated the paths, and was able to apply the patch.

I've attached 34088.2.diff

[darrenlambert]

Corrected file paths

[afercia]

Patches should be created from and applied to an install from the trunk repo, which doesn't have .rtl or minified files. They're created later during the build process :) See

I created 34088.3.diff​ from src. I tested it works well.

well pooling test

At WordCamp Philly 2017 Contributor Day we reviewed patch 34088.3.diff on a LTR install and confirmed the proper behavior on:

• Chrome Mac Version 61.0.3163.100
• Safari Version 11.0 (11604.1.38.1.7)
• Firefox Mac 56.0
• Internet Explorer 11 on Windows 7
• Internet Explorer 8 on Windows 7

To clarify "proper behavior", once the cursor left the parent item both the sub-menu and the arrow disappear without any delay.

Our group included: @rynonet, @pbarthmaier, @koakekuna

Hi, I created 34088.4.diff​ updating the 34088.3.diff​ with the CSS selectors of WordPress version 6.2-alpha-54642-src.
