No, it’s not fixed and is still here in 1.4.1 (82).
I am using a different keyboard (not stock or Gboard), and it happens not only with lists, but for any other text with me — the last character in the selection gets deleted, the selection gets dropped. It does not matter if the selection is made in the middle or the end of the note.
If only one word is selected (with or without spaces around it)— it gets deleted fine.
Two words and a space in-between is also fine! But two words and a space before or after — it fails.
A partial selection of two words works fine, but a partial one for three — fails.
This particular problem is forcing me to keep using other apps for editing notes.
