file chooser displays wrong thumbnail

[Pavol Klačanský]

Hi, I try reproduce it, but it is kind a weird.

1. Hit upload button in firefox (you need to open this file chooser dialog somehow)
2. Search for items (you need more of same starting letter, like Screenshot1.png, Screenshot2.png, ...)
3. Move with arrows on keyboard between them
4. Thumbnail on right side does not match with selected image
