Attaching video of the whole thing.
Steps to reproduce:
Create a new note
Start a new <ol> oe <ul>
Start adding some items
Goto settings and scale the text to anything under 100% (say 70%)
Continue writing the items in list
The new items added will all be 70% of each previous. After a while the text becomes so small its difficult to note what it is.
