2. Create a paragraph style without border or padding.
3. Write a title and apply the new styles.
4. Both the border and the padding from the character style are displayed.
5. Create a table of content and assign the new paragraph style as additionnal style.

Actual Result:
The title loses both the left border and padding.

Additional Info:
It is not acceptable to adjust the character style in such a way when a paragraph is assigned in an index or table of contents. Tested in LibreOffice 7.3 and LibreOfficeDev 7.4 but I think this bug is very old (maybe inherited from OOo), though I couldn't find any trace of a bug report; so I didn't specify a version. Thank you.
