Horizontal frames after section breaks in Musescore 3

Hi there,

I'm currently using Musescore 3.2.3 on Ubuntu. I have a piece with a lot of small sections which I've been separating using section breaks. That nicely causes the next section to show long instrument names:

Unfortunately if I use a horizontal frame to create space after the final barline of a section, when attaching the section break to that horizontal frame, Musescore doesn't print long instrument names for the next section as I would usually expect it to.

I use those horizontal breaks for formatting when a section is only a few bars long so that it doesn't stretch too far. Could anyone suggest a workaround? It's by no means a huge issue, but I'd love to have some way to still achieve that effect.
