Error in the Input gesture manager allowing to open many instances of them #12673
Description
Steps to reproduce:
- Open the Input gesture manager
- Shift-tab back in the filter field
- Type a string with a typo leading to no result in the tree, e.g. "zzzz"
- Press Escape to close the dialog
- Open the input gesture manager dialog
- Open again the input gesture manager dialog, without closing the previous instance.
Actual behavior:
- First errors in the log appear as soon as you type "zzzz"
- Two or more instances of the input gesture manager are opened
Expected behavior:
- No error in the log
- There should not be a way to open two instances of the input gesture manager and the usual message should appear.
