Description:
1. Even if Paragraph Style > Asian Typography > Apply list of forbidden characters is unticked, the list of forbidden characters (set in Tools > Options > Languages and Locales > Asian Layout) is always applied.

2. The bug persists even if the list of forbidden characters is edited to remove offending characters.

3. Documents that work in LibreOffice 24.2 are affected in 25.8 (versions between haven't been tested).

Steps to Reproduce:
1. Create an A4 Writer document.

2. Enable Asian Typography via Tools > Options > Languages and Locales > General >  tick checkbox for "Asian" beneath "Default Languages for Documents", and select "Chinese (traditional) from the dropdown menu.

3. Set font size of paragraph style to 14pt and page margins to "normal".

4. Edit paragraph style > Asian Typography > untick "Allow hanging punctuation", but leave "Apply list of forbidden characters to the beginning and end of lines" on. (VERY IMPORTANT: "Allow hanging punctuation" MUST be unticked, or Writer will allow punctuation marks to trail into the margins, ruining the effects described below.)

5. Paste the following text: 茲鑒於人類一家，對於人人固有尊嚴及其平等不移權利之承認確係世界自由、正義與和平之基礎；復鑒於人權之忽視及侮蔑恆釀成野蠻暴行，致使人心震憤，而自由言論、自由信仰、得免憂懼、得免貧困之世界業經宣示為一般人民之最高企望

6. At the start of line three, there should be the glyph "憤" followed by a fullwidth comma "，". In addition, a gap is observed at the end of line 2, suggesting that the "憤" glyph has been moved to the start of line 3 in order to prevent a leading comma.

7. Edit paragraph style > Asian Typography > untick "Apply list of forbidden characters to the beginning and end of lines".

8. The phenomenon described in 6. is still observed.

9. Tools > Options > Languages and Locales > Asian Layout > under "first and last characters", uncheck the "default" checkbox following the dropdown menu, and delete all content in "Not at start of line". This is the list of forbidden characters described in the dialog of paragraph styles.

10. The phenomenon described in 6. is still observed. To bring back the default list of forbidden characters, check "default", switch languages in the dropdown menu, and switch back again.

Actual Results:
The phenomenon described in 6. is always observed, regardless of the settings.

Expected Results:
In both 8. and 10., the glyph "憤" on the start of line 3 should jump back to the end of line 2, filling the gap, leaving the fullwidth comma "，" as a leading comma.
