Properly disable clicks in inactive views behind popups

[stefanhaller]

We did already have code to prevent clicks in inactive views behind a popup, but it wasn't good enough. This PR fixes two problems:

• if the previously focused view (behind the panel) was a list view, it would look like the click would select a different row, because gocui would still set the view's cursor position, which is used to draw the highlighted row
• it was still possible to click on tab headers, and this would dismiss the panel

Fixes #5256.
