Knife Tool turns text into blocks

SUMMARY
When slicing a text object using the new Knife Tool, the characters turn into plain rectangles. While the result is understandable, it's not ideal. I think the Knife Tool ought to either 

A) ignore text (good for last minute changes to comic panels after adding text) or
B) automatically turn the letters into paths before slicing (could be used to great effect I reckon).

STEPS TO REPRODUCE
1. Create a new document
2. Add some text
3. Slice the text with the Knife Tool

This was tested with Qt Platform Name:  "wayland". 
Attached is a video recording of the bug, along with additional system info.
