Description of the bug

While adding new entry in localization file idea hangs and it's JVM process keeps all cores at 100%.

Thread Dump form the time of the hang: idea-hang-thread-dump.txt

Steps to reproduce:

1. Checkout and import https://github.com/blackd/Inventory-Profiles/ at tag idea-hang-problem. The project requires Linux
2. Wait for gradle project to be imported and indexes to be created/downloaded.
3. Open platforms/fabric-1.19.4/src/shared/resources/assets/inventoryprofilesnext/lang/en_us.json
4. Try to add "": "" after the { if nothing happens move the cursor between the second ""

Expected behaviour:

Allow editing of the opened file.

Actual behaviour:

The whole IDE hangs. Most if the times event the mouse cursor disappears.
Only way to recover is to send SIG_KILL, any other signal gets ignored.

I basically reverted the bad commit and added a guard instead to avoid the error I tried to fix in the first place.

The next nightly build should be released in about 6 hours.
