Disappearing/reappearing checkboxes in collapsible block

Description

When editing a checkbox list that is inside a collapsible block, adding a new line causes the existing checkboxes to disappear. Then, adding another new line causes the first ones to reappear, and the first new one to disappear. They keep alternating every time a new line is entered. Changing notes and coming back makes the checkboxes reappear.
