Misleading number bubble on the Add Themes network admin screen

[johnbillion]

When browsing for new themes on the Network Admin -> Themes -> Add New screen, the bubble in the left hand menu which indicates the number of theme updates gets updated along with the number of results in your current search. This is confusing. In the screenshot below, it looks like I have 100 theme updates available.

The issue is the $( '.theme-count' ) selector in wp-admin/js/theme.js. It should be more specific.

What do you think of the following selector: '#wpbody-content .theme-count'? We're still targeting the main content container(in case more counters are added in the future), but we're avoiding the sidebar with the admin navigation.

The patch above uses that selector and works for me with 4.0.

.wp-filter .theme-count is probably a better one to use - it's pretty specific to that UI context, at least right now.

changed selector to use .wp-filter

In 29786:

Use a more specific selector for the count displayed on Add Themes network admin screen.
