Thumbnail full file name

In thumbnail mode
When symbols appear in the file name
there is an incomplete display of the file name
I would like to know how to avoid

For example:
How to display the full thumbnail name.jpg
How-to-display-the-full-thumbnail-name.jpg

We will be improving filename wrapping in thumbnail mode in the future. At the moment it only wraps on spaces, but we'll make it wrap on any character instead of truncating the name when there are no suitable spaces.
