Font size is not respected in lists

[DarioG]

There is some strange behaviour in the lists after upgrading to Quill v2.0.3. If you change the font size of the list and press Enter to go to the next bullet point, the font size is changed to a different one.

Steps to reproduce

1. Type * + Space and type any text
2. Change the font size of this text
3. Press Enter to write another bullet point

Expected

The font size is respected within the list

Actual

Font size is reset for each bullet point
