Rename dialog fields cut off file extensions

Thunar 4.18.7

I apologize if this was already fixed in newer versions.
In the past I think I noticed that rename dialog boxes did not adjust in width to show the full length of filenames.
This appears to now achieve this, but now I noticed that file extensions seem to get cut off by dialog input fields right edge.
At first I thought it might just be with extensions that contained more than three letters but that is not true, it happens with three letter extensions as well.
Not sure if anyone else experiences this?

Thank You
