Thanks for the quick fix. Took a look at the code and one thing is missing IMHO: exclusion of .mat-icon in addition to .mat-chip-avatar and .mat-chip-trailing-icon. Icons enable use cases such as "Filter chips" and "Action chips" as illustrated here: https://material.io/components/chips#types - therefore this use case should also be taken into account.

Another aspect of this issue discovered today - MatChipHarness.with({ text: 'xyz' }) also doesn't seem to take icons into account! This has also not yet been addressed by the PR, as far as I can tell.
