Focussing input fields sometimes does not work

[cdauth]

Sometimes the map gets into a state where input fields cannot be focussed anymore.

It seems to be a bug in angular-bootstrap and be caused by some click handler that is registered by uib-dropdown. Related issues might be angular-ui/bootstrap/#6364, angular-ui/bootstrap#6364 and angular-ui/bootstrap#6372, although those only happen from angular-bootstrap 2.3.1, in our case the issue occurs also with 2.1.4.

The issue is reproducible (but not always) by clicking on a dropdown field in the menu. After that, whenever clicking into the search input field, the focus switches back to the menu button.
