Github action views deliver less content to Firefox and Chrome than Safari

[ericpromislow]

This is probably the wrong repo, but I'm at a loss, and have to use safari now.

Trying to view the results of https://github.com/rancher/webhook/actions/runs/9473749556/job/26101987673 I can see 3 lines in Safari at the start of the run, including the syntax error in the runner which is why the job is permanently queued. But I don't see those lines in either Firefox or Chrome (all on macOS), do see them on Firefox on Ubuntu.

Safari (no bug):

Using the browser extensions, in Safari the key elements are:

div: class="uxr_CheckRun-header CheckRun-header mb-2 d-flex flex-justify-between flex-items-center mb-1 py-3 pr-3 js-checks-log-toolbar rounded-top-0 rounded-md-top-1 pl-3 pl-md-4"

nextSibling:
div: class="position-relative js-full-logs-container WorkflowRunLogsScroll"

child:
div: class="text-mono text-small py-1 my-2 mx-2 js-check-run-log-display-container"

child: 
bunch of divs and spans leading to text like
<span class="" style=""><!----><!----><!----><!----><!---->Requested labels: org-9343010-{{ arch }}-k8s
<!----><!----><!----></span>

In Firefox, I see this instead:

div: uxr_CheckRun-header CheckRun-header mb-2 d-flex flex-justify-between flex-items-center mb-1 py-3 pr-3 js-checks-log-toolbar rounded-top-0 rounded-md-top-1 pl-3 pl-md-4

nextSibling:
div: position-relative js-full-logs-container WorkflowRunLogsScroll

child:
div: js-check-run-log-display

child:
<div class="text-mono text-small py-1 my-2 mx-2 js-check-run-log-display-container">
            </div>

... notice the empty element

Chrome:

I get the same behavior happening on Chrome.

This might be a case of "doesn't work on my machine". I see the helpful text on ubuntu/firefox.

I'm not running any extensions that mess with the DOM.

Any ideas?
