Can't swap to background layer anymore when there is an emoji glyph in tab

Version 2.5b (1066) (actually happened in the version before as well)

Place this glyph :globe_with_meridians: in a tab (uni1F310), now if I select any glyph after the emoji glyph, and then I try to go to the background layer, the next glyph swaps to background instead. Only happens when the emoji glyph is in the tab is present.

We have fixed that already but need a bit more testing to release it.
