Shift-clicking works chaotically with Instagram/Unsplash

[lakesare]

Initial checklist

• I understand this is a bug report and questions should be posted in the Community Forum
• I searched issues and couldn’t find anything (or linked relevant results below)

Link to runnable example

https://uppy.io/examples

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.

#5050 fixes the issue where uppy thinks SHIFT is always pressed once it's pressed;
but doesn't fix the "SHIFT-clicking only happens if we click in a particular part of the image" issue.

I found the second issue exists in Firefox (3.35% users as per 2023 stats), however it works fine in both Chrome (64.7% users) and Safari (18.6% users) - thus making this issue not significant enough to warrant a fix (would still be nice to fix, but the fix is not trivial due to accessibility concerns!).

So we can close this issue once the 1st bug is addressed.
