Description:
I format a paragraph with a style, e.g. as a numbered list. I copy a substring of that paragraph into an empty table cell. This cell is now formatted with the paragraph style of the source. Instead, the style by which the table cell had been formatted (e.g. 'Table Contents') should be preserved.

Steps to Reproduce:
1. Format a paragraph with a style, e.g. as numbered list.
2. Format the cells of a table as 'Table Contents'.
3. Copy a substring of the styled paragraph and paste it into an empty table cell.

Actual Results:
The table cell assumes the style of the source paragraph. In the example, it becomes a row of a numbered list.

Expected Results:
The style by which the table cell was formatted should prevail.


Reproducible: Always

Additional Info:
One unwanted consequence of this bug appears in the conversion of a tabulated paragraph into a table (Table - Convert - Text to table - Separate text at Tabs): If the paragraph to be converted is one of a numbered list, every cell of the table thus produced is then numbered.
The error is more general: Upon copying a substring from any source paragraph into any target paragraph, the style applied to the source paragraph _must not_ even be included in the copy operation - let alone in the paste operation. It is not the purpose of a paste operation to destroy the style valid for its target.
This bug has been present from the very first versions of LO Writer. I had reported it years ago; but it was ignored. It causes much additional reformatting work in writing.
