Inconsistent selection behaviour of 'Add tag' dialog when using CTRL+A shortcut

[ff5722]

What steps will reproduce the problem?

1. Select an object and open the Add tag dialog using the CTRL+A shortcut

What is the expected result?

The tag or key is always pre-selected

What happens instead?

Sometimes the tag or key is selected, sometimes the cursor is at the end and nothing is selected. Curiously, when using the mouse to click on the Add tag button it always works fine as on previous versions.

Please provide any additional information below. Attach a screenshot if possible.
