I don't have an example of your situation, but the similar situation
of a rename with modifications works fine for me.

It's possible SVN doesn't expect you to make changes on the branch
operation so it takes shortcuts trying to come up with a previous
revision, I don't know. Underneath, it is a copy-with-history
operation, which is the same as a rename, so I'm surprised rename
works but branches don't.

At least you have a workaround, I guess. What if you double-click the
file in the first branch revision, when you do not have stop-on-copy
selected? Obviously TortoiseSVN has the required data to do what you
want, I'm perplexed why it wouldn't.

I think I'd consider it a bug. But then, my advice is actually "don't
do that". Why do you find it necessary to branch from a modified
working copy? You could just as easily branch from the parent revision
of the working copy, switch to the branch, and take your uncommitted
changes along with your working copy to commit later. I think this is
the usual method, and probably better supported seeing as how
branching from a repository revision is the default selection on the
branch dialog.
