Changing banks refills the dropdown. This cannot be avoided
since unnamed banks are not in the dropdown, and the dropdown
content can change dynamically. Scroll-wheel does not work reliably.
On macOS, `context->get_targets ()` may be empty when dragging.
In this case the Clip-Picker assumed that a slot is about to
be dropped and switched to the local clip library.
This in turn cleared selection and it was no lnger possible
to drag any clip out of the library.
When auditioning is started, transport controls are disabled
via `set_transport_sensitivity(false)`.
This prevents <space> from being handled:
DEBUG::Bindings: binding for Key 32 (space) state 0 : Transport/ToggleRoll - insensitive, skipped
So the key event is passed on, and can reach the clip-picker treeview
where <space> selects and/or activates a row, which re-starts
audition.
ARDOUR_UI::toggle_roll() cancels audition when audition is active,
so this action should be sensitive, even while auditioning.
For example, the following log text creates a markup error that results in
the session loading dialog being completely empty.

The explicit disconnect in the destructor prevents any more signal->connection firing, but the invalidator
is required to remove existing queued slot calls in the receiving thread
Note: this still seems suspicious: we explicitly disconnected from signals in the destructor. However,
it is better form to be able to use invalidator() in the connection call
This just uses the old Evoral BeatTest. Some of the tests needed amending
because temporal uses rint() to convert between float and int, not just
a cast.
Until we have a trimmer, the clip length spinner sets integer beats (beatcnt)
This allows the user some minimal ability to fix a clip of the wrong bpm.
We assumed that 'clips' are already be pre-trimmed to a beat length.
Our internal heuristic always forced tempo to match an integer beatcnt
However: when bouncing a Range to a Trigger Clip, you can know the tempo, and also have a non-integer beat length.
In those cases, the clip-length spinner could behave oddly.
While it's arguably wrong to show integer beats when the internal value is something else,
we still want to show the spinner in integer beats, so it remains usable for its main purpose
