  • Fixes the arrow in the expansion panel header not being quite centered, due to it being based on a rotated CSS triangle. These changes switch to use an SVG which is much easier to reason about.
  • Uses the correct font weight for the panel header's title.

font-weight styling should go into @mixin mat-expansion-panel-typography.

This is inside the typography mixin already.

I see that you just added the pr: merge ready label, but the following checks are still failing:
    failure missing required label: "target: *"

If you want your PR to be merged, it has to pass all the CI checks.

If you can't get the PR to a green state due to flakes or broken master, please try rebasing to master and/or restarting the CI job. If that fails and you believe that the issue is not due to your change, please contact the caretaker and ask for help.

fix(material/expansion): center indicator icon in M3
49fc6fc 
Currently the expansion panel arrow is drawn with borders which makes it difficult to center. It's also problematic in high contrast mode where it renders as a rectangle. We've wanted to fix this for a while, but it breaks a lot of internal screenshot tests (see angular#10503).

These changes resolve the issue for apps using M3 by having two indicators that we toggle using tokens.

Fixes angular#28037.
