Weird issue with "H2Push" combined with FilesMatch

[Jose Stefan <josestefan@xxxxxxxxxxx>]

Hello,

I have a weird issue while using "H2Push". I'm turning it off, but depending where it's nested it doesn't work as expected. Subset of config shown at the end. I'm using version: 2.4.52-1ubuntu4.6 on Ubuntu 22.04 LTS.

With the code as presented, it still triggers a push for "fileC.css". I expect NO push to happen as it is turned off before the"H2PushResource..." line.

Here's where I'm confused. I've performed the following individual tests:

• If I use the "H2Push off" outside of the FilesMatch (and comment the one inside), The push doesn't happen.
• If I use both "H2Push off" and "H2PushResource..." outside of the FilesMatch (and comment the ones inside), The push doesn't happen.
• If I comment out the "H2PushResource..." inside the FilesMatch, the push doesn't happen. Therefore, I know the config is hitting that part.
  

It's only when both lines are inside the FilesMatch that I don't get the expected results. Yet the context for h2push reads:

Context: server config, virtual host, directory, .htaccess

The plan, eventually, is to enable just the early hints and not the push. But I haven't even gotten to testing that part yet. My version of httpd doesn't support "H2EarlyHint".

Subset of the config:
