Thanks for your feedback and the detailed description of the issue. I think I've read this before and it's very similar to what has been described here:
List focus jumps to first column after selecting multiple rows
Unfortunately, it's one of the open bugs and I have currently no idea on how to fix it. I'm looking into it from time to time, with the hope of finding something, but so far it's been not successful.
I'll definitely keep and eye on it and keep you posted when I find something.
