bug(MatListItem): Misalignment of Button Icon in Two-Line MatListItem

[Zerbus]

The previous version in which this bug was not present was

16

Description

When using a Button Icon as matListItemMeta in a two-line MatListItem, the icon is not properly centered within the button. This misalignment appears to be caused by the display: inline-block; property in the .mdc-list-item--with-trailing-meta.mdc-list-item--with-two-lines .mdc-list-item__end::before selector.

Expected Behavior

matListItemMeta is meant to be used as a container. Something like this should work:

<div matListItemMeta>
  <button mat-icon-button>
    <mat-icon fontIcon="home"></mat-icon>
  </button>
</div>
