With space placement set to 'after output', trailing '/' characters blocks OK button in add translation window

[Anodynous]

Describe the bug

With space placement set to "after output" a trailing '/' character is appended to the end of the outline, causing the OK-button to be grayed out. Manually deleting it enables the OK button making it possible to add the new translation. With spaces added before output the issue is not present.

To Reproduce

Steps to reproduce the behavior:

1. Set space placement to "after output" in configuration
2. Open the add translations GUI
3. Add stroke(s)
4. Add translation
5. Remove trailing '/' character from strokes outline in order to enable the OK-button

Expected behavior

Translation is possible to add regardless of space placement without the need to remove the trailing stroke-separator character from the outline.

Screenshots

Trailing '/' character prevents adding translation:

Deleting the last '/' character of the outline enables addition of translation:
