* Reverts #201
* Closes #205

The update to egui 0.27 broke scrolling and selection of scopes in the
flamegraph.

I'll revert it, and then we don't merge things without testing them next
time.

### Description of Changes
In the version `0.27` release of `egui`, the interaction handling was
changed. This caused the scope selection in the flamegraph to be
unselectable. By disabling the `drag_to_scroll` on the related
`ScrollArea` this issue is solved.

The latest scope selection does not suffer from this, as it does not use
a `ScrollArea`.

Note that this does not have any behavioral effect, but instead results
in the same behavior of click/drag/scroll when on egui `0.26`!
