Tooltips / Pointers cover theme detail modal in admin

[krogsgard]

Tooltips or pointers or whatever they are called -- they are covering the modal for the theme detail screen in the WordPress admin. I'm not sure if we should trigger it to be dismissed if ignored, or adjust Z-index of the modal, or what. But it's not very pretty as is.

We should look at this.

z-indeces should die in a fire.

Another way to deal with it would be to hide the pointer when the modal is open. The modal has a short animation on close, that prohibits the pointer from reappearing until after that animation has finished though, which looks a little awkward.

Don't let wp-pointers cover the theme detail modal.

Fixes #31544.

Admin bar z-index bar

When there's only one theme installed the theme browser only shows the modal without a way to close it. Unfortunately the new z-index is covering up the dropdown menus in the left admin menu.

In 33111:

Respect the special case of having only one theme.

If there is only one theme, the Pointer won't show and the overlay is active by
default. In that case the overlay covered submenu flyouts, after [33068].
Without the Pointer active, there is no need to bump the z-index, so it can
remain at 10.

Fixes #31544.
