Description Real Ice Cube 2022-09-02 02:40:01 UTC 
Description:
When creating a list that is indented (with TAB), items c and d will always lose their indent.  Tried on multiple computers running Windows on new and several older versions of Writer.  List ends up looking like below:
   a)
   b)
c)
d)
   e)
   f)

Steps to Reproduce:
1. Type "a." or "a)" with text after it.
2. Repeat for "b." / "b)" and so on
3. When you get to "c." or "c)", the indent will be lost.  Also happens for "d." / "d)"
4. Indent returns for "e." / "e)" and following letters.
5.  Problem will not occur unless text is following the items on the list (not just a, b, c, etc.)

Actual Results:
	a) first item, retains indent when I press “enter”
	b) second item, retains indent when I press “enter”
c) third item, LOSES indent when I press “enter”
d) fourth item, LOSES indent when I press “enter”
	e) fifth item, retains indent when I press “enter”
	f) so do the rest

Expected Results:
	a) first item
	b) second item
	c) third item
	d) fourth item
	e) fifth item
	f) etc.


Reproducible: Always

Repro using Version: 7.4.1.1 (x64) / LibreOffice Community
Build ID: 0a046a10cbf1679eea5538bd3ab63156caa3a036
CPU threads: 12; OS: Windows 10.0 Build 19044; UI render: Skia/Raster; VCL: win

If you enable "Bulleted and numbered lists" under AutoCorrect Options (Options tab), it would change a bit: for a and b, it would work the same, but for c, it turns the line into a *numbered list*, using *roman numerals* (so after pressing Enter, the next line is automatically numbered "ci").

Disabling "Delete spaces and tabs at end and start of line" has no effect on this.
But disabling autocorrect while typing as a whole fixes this.

Using OOo 3.2.0, the picture is the same.

It looks that the problem is somehow related to the automatic recognition of Roman numerals. It works erratically, though: it should not affect the text when the "Bulleted and numbered lists" is disabled (the default now).

By the way, the same problem happens when you type "<tab>1. blah", which confirms the list detection theory.

But disabling "Delete spaces and tabs at beginning and end of paragraph" avoids the problem.
So it looks like the "Delete spaces and tabs at beginning and end of paragraph" only works in conjunction with other matching rules (even disabled, like numbering) - so looks like a bug in "Delete spaces and tabs at beginning and end of paragraph". It likely should work regardless of the other matching rules.

A possible code pointer: SwAutoFormat::DeleteLeadingTrailingBlanks in sw/source/core/edit/autofmt.cxx.
