"ReferenceError: Iterator is not defined" on dev.track-oot.net

[thecnoNSMB]

What happened?

I reported this to the developers of the track-oot website on their Discord, but they've told me that this must be a bug with the web browser, citing the MDN docs page for the "Iterator" object. According to their testing as well as mine, this issue does not reproduce on Firefox. The bug does reproduce in private browsing and when disabling extensions that are most likely to cause issues such as ad blockers.

Reproducible?

• I have checked that this issue cannot be reproduced on Mozilla Firefox.

Version

G6

What platform are you seeing the problem on?

Linux

You have failed to supply STR, and just loading the site and clicking around, i cannot.

What is STR?

Oh, it must stand for "steps to reproduce". The steps to reproduce are to load the Linux binary of Waterfox (I'm on v6.5.6, on Nobara, a Fedora 41 fork, running KDE Plasma with Nvidia graphics, just in case any of that matters) and simply navigate to the website, no interaction with the page is required. The issue I'm experiencing prevents the webapp from loading entirely.
