🍳 `puffin-egui`: Incorrect flamegraph frame selection input handling

[tosti007]

Describe the bug
With prior versions it was possible to select a specific frame within the flamegraph viewer. With the lastest version selecting a specific scope focuses the ScrollArea wrapping the lists of scopes instead. I think this is due to egui v0.27's changes to how input handling is performed.

To Reproduce
Steps to reproduce the behavior:

1. Run the eframe.rs example.
2. Open the flamegraph.
3. Pause the frame collection with space.
4. Select any of the previous frames.
5. Notice that this is not possible and scrolling is activated instead.

Expected behavior
I expect to select the frame I clicked on, as was the case with egui v0.26.

Broke by #201

This was accidentally closed through #211, as I phrased my sentence unclearly. After that PR the issue is still present for me.
