Disable/Re-enable UI is confusing

[dhowe]

v3.18.0

Disable UI is confusing: not clear after clicking disable whether one needs to click again on domain to make the disable active.

I think a better solution might be to always pop-up the page or domain option without any preselection. Then the user must select one or the other, which causes the pop-up to close

There also seems to be no way (at least sometimes) to un-disable a site/domain (see image below, where clicking on disable for the already disabled site does nothing. How is this supposed to work ?
