IDE text mixup

App puts the "}" bracelet automatically after writing "{" and hitting enter after it.

If i write { and do not hit enter (i need to remember to put it later) after copying / pasting / undo / redo shortcuts the code starts to appear in wrong places and is mixed. Saving project usually does not save the mixed text, but after that the app needs to be restarted.

Reproduce the issue in the Arduino IDE by entering an opening brace, using copy/paste and undo/redo, then saving the project. Trace the IDE text-editing path involved in automatic closing-brace insertion and verify that text remains correctly ordered and is saved without requiring a restart.
