PM bug report: Repeated CSS file downloads.

[BenFenner]

I'd been working on finally implementing asynchronous jobs for my web site, and in the madness I noticed (and at first thought it was related) that one page in particular (sorry it's behind an admin login wall) shows in the Network tab of the dev tools that my "main.css" file is downloaded twice. This first one is a 304 response, the second one that comes later in a 200 response. It does not do this for an otherwise nearly identical page (behind a super-mod login wall). I ended up searching for the issue and ended up finding this!

(From here: https://stackoverflow.com/questions/426 ... aded-twice)

I checked Firefox ESR 115 and it's not showing the same behavior, so presumably they fixed it at some point.
And of course I only have one reference to the CSS file in question in my HTML, and it is not cyclically loaded...

I wish I could give a working example that's not behind a login/permissions wall. I will see if I can find one.

Edit: I went to go take a screenshot to better explain the situation and what type of response I was getting (the 200 response was for "[JS] stylesheet" which was very odd). But I can not longer reproduce the issue. Soooooo.... Never mind. =/
