Attachment: Network capture showing H2 push happening

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/101.0.4951.64 Safari/537.36

Disable Caching by checking "Disable caching checkbox"
CTRL+F5 to reload the page
Page does not load properly.
The core file : https://e-services.blum.com/bba-res/resources/blum-ui-core.js. needed does not load as per Firefox network tab.
The file is subject to H2 push.

FYI currently the issue is no more reproducible as H2 push on server side has been disabled.

HAR, Firefox http traces, pcap will be shared for situation when issue happened.

Actual results:

.js file did not get loaded by browser and computed which cause the page not to be loaded.

Expected results:

The js file should have been loaded and computed.

It looks like similar to what was seen in https://bugzilla.mozilla.org/show_bug.cgi?id=1687606 (visually) in the network tab.

The Bugbug bot thinks this bug should belong to the 'Core::Networking' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Fixed by disabling HTTP/2 push in bug 1915848.
