@pmusaraj Some existing icon classes are not working after the icon upgrade. For example `map-marker`, e.g.
Seperately, would it be possible to retain a fallback to the existing font-awesome icon fonts? The new svgs are great, however the hard cutover means that you have to use the `icon-library` helper methods everywhere right now.
Basic icon html, e.g.

```
no longer works. Which is fine long term, but it means all existing implementations like this broke on the upgrade.
If this is not possible then no worries. I’m going through all my plugins right now anyway.
