Steps to reproduce

1. Go to Instagram/Unspash
2. Click on one of the images
3. Shift-click on some other image

Expected behavior

We expect it to work like it works in Google Drive e.g., all intermediate files get checked.

Actual behavior

First of all, click only happens if we click in a particular part of the image. Secondly, SHIFT never resets, and the app always behaves as if SHIFT is pressed from then on.
