Dashboard briefly flashes `isDraggingOver` off while dragging over drop zone. #5392

Initial checklist

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

Link to runnable example

https://uppy.io/examples/

Steps to reproduce

Drag image over dropzone but do not release. Slowly (while dragging) hover over dashed line or "drop files here" / images.

Expected behavior

When dragging over dropzone uppy should not flash between hover state and non hover state.

Actual behavior

Uppy flashes and briefly toggles the uppy-Dashboard--isDraggingOver class on the dashboard div.

Are you on the latest release, which has the anti-flickering fix: https://github.com/transloadit/uppy/pull/5326?

WesleyKapow commented 2 months ago

@Murderlon yes on latest, and this happens for me on uppy's own example site as linked in the issue.

Also just tested browsers:

Chrome (latest v 127.0.6533.89) has the bug.
Safari mostly doesn't have the bug (if I move the dragged image around for a while I can get a single flash.. so not really a problem)
Firefox, no bug (couldn't get a single flash)
