I installed Sublime Text on my Archlinux and tested with the C++ code OP posted.

What I see is that ST does seem confused about indentation, while trying to make
a newline right after `slots:` line.

However, if you try to make a newline after the `void someSlot() {};` line, it
will use the indentation used on the previous line.

The default cc-mode in Emacs works similarly. The cc-ts-mode on the other hand
doesn't make use of the previous indentation, and I think it should. It would
resolve that problem and others, because in my experience it happens very often
in C and C++ code that you want some custom indentation level, so you just make
one and you expect the editor to keep it while creating more new lines.
