Logs dialog command line vanishes when highlighted

Docker Desktop for Mac
1

Expected behavior

Clicking a highlighted section for copy&paste should not be modifiable.

Actual behavior

Typing any character after highlighting the text allows for user modification of the dialog.
Does not persist after closing and reopening, so minor usability bug.
