Found by mbasti during reviewing vaults. There is a bug in adder dialogs which have dropdown field. When the dropdown field is focused and the dialog is closed using ESC button, the adder dialog cannot be reopened.

Steps to reproduce:
a. go to any page which has adder dialog with dropdown field
b. open adder dialog
c. open dropdown field and don't click on anything
d. press ESC (dialog should disappear)
e. try to open dialog again
f. dialog shows and immediately disappear

Workaround:
It helps to switch to another facet and return back, then the dialog shows.
