Card Data Description editor can't tab over to next element

[StefanoFiumara]

Currently, when using the Card Data Editor, it is possible to use the Tab key to switch between form elements in the control.

This works for every control except for the Description editor, which uses a multi-line TextEdit control node. This node swallows the tab key input and inserts a tab character inside the description box instead of allowing it to switch focus to the next element in the form.

Adjust the control so that the tab key is not swallowed and the entire form can be navigated in this way.
