[CALC] FORMATTING Insert line above current line uses wrong format

Steps to reproduce

(1) Open Calc,
(2) create some entries for a small table (e.g. 5 columns). Table has a header and some rows with data.

(3) Change header line format to have yellow background of cells, increase text size of header cells.

(4) Click first cell in first row of data (1st row below header).

(5) Select full first row of data (the same row that you have just clicked first cell of)

(6) Right click mouse to open context menu. Select "Add line above"

(7) BUG: Calc will insert a new line below header, but instead assigning the same format to it as data rows have it will copy header format (i.e. yellow background, bigger text size).

Expected behaviour: newly inserted line should have same format as first data row has because that is from where whole procedure started.

Same happens (but less an issue, more expected) when using "insert line below" when starting from header row.

When I select a row and use "insert line above/ below" I expect CALC to use the same format for newly inserted line as has the line that I have selected to start inserting above/below from.
