In the time_resolved_fly_and_collect_with_static_seq_table plan stub I have had to change the collect_while_completing stub call back to the code used for the i22 experiment as the new code just hung.

An issue that was raised back then has not been addressed but i'm not entirely convinced this is the full problem. The issue and following discussion is here bluesky/bluesky#1630.

This needs investigating.

It seems to be working with the latest version of ophyd async main d7f0748 with the following change

The plan used to test this was
