gosling-lang / gosling.js

I found the issue in the GIVE example on the Editor (https://gosling.js.org/?example=GIVE) and also in the Gosling Designer that uses the most recent Gosling version.

I can reproduce this by zooming in (e.g., seeing a few hundred BPs), panning, and then zooming out quickly.

I see the following error message:

The maximum call stack error is coming from the following code:

gosling.js/src/tracks/gosling-track/gosling-track-model.ts

Line 82 in 9ecd4d3

this.specComplete = structuredClone(spec);

Interesting! That line was added in this PR. I'll look into this.

Synchronous navigation of tracks seems broken
