OS: Windows 11 64bit
When I generate a "Video thumbnails gallery" for a video, if the video filename contains a dot/period ("."), when I try to save the generated file the suggested filename is truncated at the first "." in the name.
Effect: Wrong filename on save.
To reproduce:
1. Name a video with one or more dots in the filename.
2. Create > Video thumbnails gallery > (any settings)
3. Attempt to save the generated gallery. Both "File > Save" and "File > Export" have the same issue.
Actual behaviour (bug): The suggested filename is truncated at the first dot

Expected behaviour: Suggest the full filename, no matter how many dots are present in the original video filename.
