THX "Customize" button not working as expected

[jacklenox]

On the new theme page, when you press the "Customize" link on the thumbnail for your active theme, it just shows the theme information with another link to "Customize". So you have to click "Customize" twice in order to actually reach the Customizer.

The problem appears to relate to the div containing this link (.theme-actions) having position: absolute but with no z-index defined. So it is masked behind the parent div (.theme) which has its own related action when clicked.

There is a very easy fix which I'll upload to this ticket by way of a patch almost immediately. If .theme-actions is given z-index: 1, the "Customize" button works as expected.

Themes: Fix the Customize button for the current theme. Props jacklenox. Fixes #26214

Thanks for the fix. For reference, this was triggered by an mp6 z-index fix that further forced another z-index update to the themes code, which lead to this issue.
