Huge memory leak in Firefox!

[Openstreetmapler]

When I loaded the volcano example in my Firefox 128.0.3 browser, the RAM spiked heavily, as the website now uses several GIGABYTES of RAM!

=> Unusable!

While writing this, RAM usage increased to 6 GB for a moment! There’s a memory leak for sure!

By the way, I also use uMatrix.

Screenshot

Leftmost yellow spike in the graph is when I loaded the page.

These errors appear in the browser console during the 6 GB RAM spike (notice the JSON data being over a billion characters long):

While I know what the issue is, it'll require some architectural changes to fix. I've started working on something, but I'm already occupied with other projects for at least the next three weeks, so I wouldn't expect to have something ready before August.

[Openstreetmapler]

Okay, I won’t use the tool until then.
