Error found with slurs overshooting using two voices

Take a look at the .gif file provided:

Using two voices, when entering a slur while in note-entry mode and then continuing along, the slur seems to be miscalculated (v. 3.3.2). Included in the capture is also doing a post note-entry of a slur showing that it works just fine outside of note-entry. Not sure what's happening here, but seems to be some sort of error that needs to be re-checked? Hopefully it's reproducible for the sake of understanding what's happening.

P.S. It's not to do with the augmentation, as it still does this if the second note is for example a quarter note.
