Changing view from Handsout to Normal triggers master slide

Hi,

I'm viewing a presentation now in LO 5.1.2 and if in the main section I choose Handout view (first is Normal, then Outline, then Notes, Handout and Slide Sorter) and then I choose back Normal -- LO is serving me a Master slide setup.

It's not doing it if I choose e.g. Outline and then go back to Normal. It's only doing this from Normal → Handout → Normal [→ Master slide].

Should that be reported or what?
