IllegalStateException while typing changeset comment

[gaben]

What steps will reproduce the problem?

1. Type something in the changeset comment field

What is the expected result?

No exception.

What happens instead?

IllegalStateException after nearly all words and the comment is randomly split into lines that wasn't even possible in previous versions.

Please provide any additional information below. Attach a screenshot if possible.

I don't know if it's reproducible :/ Maybe something to do with #20690?
