Description Eyal Rozenberg 2022-02-26 21:24:24 UTC
Description:
I have this large .doc file which I imported into LO Writer (unfortunately I can't share it here). When importing this file, the import filter generates 40 (!) different numbering styles; however, when I view the "applied styles", I only see 14 or 15 of these.

Now, if it were some named style which was stored in the MS-Word file and imported, then - fine, I can live with that. But these are styles named: WW8Num01, WW8Num02, etc - so, these must be generated based on anonymous styles or manually-applied formatting.

I claim that no such style should be generated unless some text in the imported document actually uses it. Alternatively, if a style is generated in a preliminary step, and it is then determined the style is not in use - it should be deleted.

As for the minimum affected version - I remember this since forever, but I haven't actually checked. It's probably inherited from Open Office.
