Scrape metadata of selected episode(s) does not preselect Thumb

What tinyMediaManager version are you using?

Version 5.1 nightly

What is the actual behavior?

When choosing Scrape metadata of selected episode(s), Thumb is never preselected.

What is the expected behavior?

That it is preselected (in the tv show artwork fielenames settings, I have selected <dynamic>-thumb.ext) and the thumbs are scraped when I scrape an entire tv show so it seems to be limited to Scrape metadata of selected episode(s).

Steps to reproduce:

1. Open a tv show.
2. Go into a season.
3. Select an episode.
4. Right click → Scrape metadata of selected episode(s).
5. Open the dropdown list for Scrape following items.
6. Notice that Thumb is not selected.
