I have a PR open that will greatly improve the cursor/placeholder handling during multiple file uploads

[https://github.com/discourse/discourse/pull/13907](https://github.com/discourse/discourse/pull/13907)

If all of the following are true:

- You don’t care about storage costs

You may want to either disable the feature or tweak the threshold for minimum size up a few megabytes.
