Fixes #10146

We have a setting in the Accounts Window now

Previously only application default values were possible

This helps the Window Manager decide how to display the window

This is a more flexible approach

default_text is returned if the value of the setting is an empty string

If the input textview is not sensitive it can’t get the focus. In that case propagate_key_event() would send the event again to the conversation textview. This would mean a recursion.

Fixes #10259

This allows other widgets to handle the ESCAPE Key first and only
if not other widget handled the key press exits the dialog
