Sample ODT

Open the attached document that has a bulleted list, and two rectangles positioned to displace some of the items.

Note the following problems with the 3rd list item: 
- should start with "123456" but only "23456" is shown,
- the item starts further in compared to the others.

If you delete the blue rectangle, you can see what the list item should look like.

If you resize the red rectangle vertically so it ends at around where the blue rectangle starts, the item changes, now all the characters are shown, but the item has two bullets, which is also wrong.

Observed in LO 26.2.0.0.alpha0+ (750ac43647526525c425124f601112b64c8e8f46), and in latest of 7.6 bibisect repo / Windows.
Between 3.3 and latest of 7.5 bibisect repo, the list item looks like the result of the above described resizing initially (the size of the shape doesn't change): all the characters are shown, but the item has two bullets.
