Removed review request as icon size shrunk when I made the viewport bigger, looking for workaround

[jancborchardt]

Looks really nice! ✨

[marcoambrosini]

Fixed the size issue, ready for review now

If an animation is necessary I like this better than the previous proposal. Looks nice :)

[jancborchardt]

Seems good to go then, right?

@marcoambrosini does it work gracefully when:

• focusing instead of hover
• stopping the hiver befire the animation is done (could just finish the animation)
• staying on hovering (either is fine: only animate once, or repeat as well)

[marcoambrosini]

@jancborchardt as of now focusing does not trigger the animation. Should I add it?

[jancborchardt]

@marcoambrosini I'd say generally we should treat hover and focus as close as possible, so yes. But it's not a blocker.

[marcoambrosini]

Gave it a quick try and this is a bit complex. I will reference in new issue

[julien-nc]

Do you want to add that to the NcAssistantIcon component of nextcloud/vue as well?

[marcoambrosini]

That would result in this animation being in many other places right? I think it would be better to avoid that for now
