What are those warnings and why does PostCSS spit them out?
I'm not convinced this is the right fix. I have a hunch this happens because of outdated packages
Using justify-content: start is completely valid in this instance and I would not want to change our code to satisfy this tool's incorrect expectations

Essentially the same PR as #9500.

As I myself am not annoyed with these warnings, it's ok for me to close this.

What do you think?

[germain-gg]

I understand what you're getting at, I'm just not sure this is how we should approach it.
We're changing our codebase to satisfy a tool that has a wrong assumption, I'll bring that up with a few other folks as it does not seem we have consensus on the matter

Might be reopened after element-hq/element-web#23597 is resolved.
