Selection window cutting off the content at the bottom in some themes

[fernandoepm1]

Describe the bug
When trying to perform the game selection for HowLongToBeat in certains themes, the Confirm and Cancel selection buttons are clipped at the bottom
This bug is happening in NovaX, Stardust and Stardust (Legacy) and probably some other themes also.

To Reproduce
Clicking the HowLongToBeat button in the games detail page to open the selection window in certain themes

Expected behavior
The selection window should be more flexible and have adjustable size to the content to be able to view the contents at the bottom, quoting darklinkpower: "fixing it could be as easy as setting the window SizeToContent property" (darklinkpower/Stardust#53 (comment))
