Japanese text doesn't truncate properly using fyne.TextTruncateEllipsis #4998
Description
Checklist
- I have searched the issue tracker for open issues that relate to the same problem, before opening a new one.
- This issue only relates to a single bug. I will open new issues for any other problems.
Describe the bug
When truncating text in a label, richtext, etc. Japanese text (and possibly other scripts too) don't truncate at the right position and instead overstep the boundary of the widget.
