Thunar 1.6.15 on Bionic 18.04, kernel 4.15.0-23-generic x86_64. Behaviour seen on earlier Xubuntu versions as well.

To reproduce:

1. Open a Thunar file manager window at a directory containing sub-directories (e.g. a home folder)
2. Open one of the sub-directories in a new tab (right click or middle button) (e.g. ~/sub1)
3. Navigate to any next-level directory (e.g. ~/sub1/sub2)
4. Click the back/previous button (not "up")

What should happen:

You end up back in sub1, which is the root directory of that new tab

What does happen:

You end up back in ~, which is the root directory of the *parent* tab in that window. Any subsequent child tabs will exhibit the same behaviour, i.e. opening another tab on ~/sub1/sub2/sub3, go down one more level and back and you'll end up back at ~.

This appears to be limited to the "previous" function, so it's something stack-related - probably, taking the value off the parent stack instead of a tab-specific stack, if I had to guess. "Up" works as intended.
