On web, zoom followed by pan causes havoc

This is on the https://www.ventusky.com webapp.

1. Move the mouse wheel one notch to zoom in or out.
2. Quickly (within a second or two) click and hold the left mouse button, drag the map a tiny distance, and release.
3. The pan and/or zoom does something completely unexpected. I am usually teleported to the other side of the map.

This is 100% consistent for me, i.e. the problem happens every time I follow the above steps. Waiting a few seconds after scrolling with the mouse wheel avoids the issue. I'd be happy to send a video.

I'm using Chrome on Windows 11 but I've seen this on multiple machines over at least the past year or two.

I hope this is a useful report. I love this product, it was an invaluable resource which I used every day during my round the world bicycle trip. Keep up the good work!

Extra info: in step 1 of the repro, you can click the +/- zoom icons instead of using the mouse wheel to zoom, and the problem still happens.
