Sometimes, there is an unexpected character limit when renaming or saving a song (even shorter than the actual song title).
It only occurs after a similar popup was shown with such a character limit.

Reproduction steps:

1. Click "Rename" on a a song with a very long title: the title shows up entirely.
2. Open a popup similar to the song renaming popup (ie attempt to destroy a rare or epic item)
3. Click "Rename" on a a song with a very long title: the title is truncated, no more characters can be typed.
