Tab key doesn't work in multiline string setting textarea

Testing #79571

This issue is to note that the tab key doesn't work in the multiline string setting textarea, because tab is used to move focus to the next element.

The monaco editor uses Ctrl+M to toggle between two modes: tab meaning to move focus, and tab meaning to insert a tab character into the editor. Maybe the textarea can do something similar?
