Hello,
in one of my projects I need to update a select based on an other select. I've worked out a working logic for that but during testing i noticed, that after a few changes (5-6 times) the update process starts lagging. I also tested the logic with plain jquery / html and there the problem does not occur. I also tried to destroy und recreate the select, but that didn't work either and as I read in an other question this is not longer necessary as the select automatically updates.
Any idea how I can fix the issue?

Expected behavior
Updating of a select works smoothly all the time.
