Changing font on multiple sourceText keyframes works inconsistently between Properties and Character panel

Use scenario:

Being able to change the font or font properties on text layers with multiple sourceText keyframes. Only realised today that the Properties panel and Character panel behave differently when taking the same steps. I have been manually updating each keyframe because I thought this didn’t work and I was mis-remembering having done it in the past 🤦🏾‍♂️

Steps to reproduce:

• Create a text layer
• Set multiple keyframes on the sourcetext property
• For ease of comparison, duplicate the text layer and move so both are visible seperately
• On text layer 1, select some/all keyframes, ensure the playhead is on a selected keyframe
• Using the Properties panel, change a setting’s value (e.g. selected font, change font weight or size)
• On text layer 2, do the same operations, but use the Character panel instead.
• Then move the playhead between keyframes to see the result

Result:

On the layer where the Properties panel was used, only they keyframe under the playhead will have updated with the change.

On the layer where the Character panel was used, all selected keyframes will have the change applied.

Expected:

The Character panel gives the expected result - that the same change (e.g. change font) will apply to all keyframes selected. This is consistent with other multi-keyframe edits (e.g. selecting multiple position keyframes, then dragging the value of the one the playhead is over to change them all by the same amount).

As a user, I’d expect the Properties panel behaviour to match the functionality of the Character panel, which I’d class as the expected behaviour, given the other systems in AE.
