Fix Touch Behavior Cancelled too fast if user just tap it once

[albilaga]

Description of Change

When user tap the button or element that have TouchBehavior, the TouchBehavior animation didn't respect DefaultAnimationDuration to finish the animation. So basically after user tap it will directly cancel and it will throw stacktrace

System.Threading.Tasks.TaskCanceledException: A task was canceled.

System.Threading.Tasks.TaskCanceledException: A task was canceled.

This PR attempt to fix that by waiting with Task.Delay from DefaultAnimationDuration instead of just directly abort it

Does your change handles double-tap? If so, how is the behavior?

Based on the referenced issue this fix doesn't solve that problem. I asked the author to open this anyway to show what they had and we work through it. I've added a review comment to show what I think might be the fix. I'll try and test it out later

Yeah, I asked that, because (for me) would be odd to have the animation going on after I release the button, or if I double tap it, would that replicates two animations, if yes, that could cause some confusion on the user...

@pictos here is the result when double tap. As you thought it is like handled by two animations. here is the attached result

so you suggest to like giving throttle to ignore the next tap? or how it should be

@bijington I don't see your review or I miss something?

Btw I change it to draft because I don't think it is ready yet

[pictos]

@albilaga I believe the control should ignore any other touch while animation is performing. Since this is a single tap instead of a double-tap gesture. For me, at least, feels wrong having that behavior

[albilaga]

@pictos testing with native android with button pressed state it will just do pressed state again without ignoring the second tap?

Hi @albilaga! Could you update this PR to resolve the merge conflicts?

We've finally merged the massive .NET 9 PR today and it introduced a few merge conflicts across our open PRs.

[albilaga]

Hi @brminnick will do. this week hopefully can do resolve merge conflict. still got some fever 🤒🤒🤒

[albilaga]

Hi @brminnick , PR already reabased

[TheCodeTraveler]

Thanks @albilaga! We reviewed this in our January Standup and we decided that the best way forward is to make this behavior configurable.

@jfversluis Will be opening a New Feature Proposal to include the details discussed in the standup.
