TextContentRenderer: ListItem renders too many spaces

[sperol69]

Steps to reproduce the problem (provide example Markdown if applicable):

List:
1. 2) 2026.
end

Expected behavior:

List:
1. 2) 2026.
end

Actual behavior: (too many spaces, increasing times after times)

List:
1.    2)       2026. 
end
