Description:
I added a largish comment to a cell in the first row so it is in a box which is taller than the row's height. I froze the first row. When I scroll down I can hover over the comment and it is displayed correctly.

However:

If I set the comment to "Show" and scroll so the sheet goes up (scroll down), the part of the comment which is below the first row goes up with the rest of the sheet.

Steps to Reproduce:
1. Start a new spread sheet
2. Right click row 2 and select "Freeze Rows and Columns"
3. Right click cell A1 and select "Insert Comment" and paste the following in to the comment box:

This is a long comment which goes over more than one row

4. Left click cell A1 to make the comment hide itself

At this stage scrolling the sheet up and hovering over the comment marker works fine;

BUT:

5. Right click cell A1 and select "Show Comment"

At this stage scrolling the sheet up scrolls the bottom half of the comment up as well so that you can only see:

This is a long


Actual Results:
Truncated "shown comment" on scrolling

Expected Results:
We should be able to view the whole comment on a frozen row when the sheet is scrolled up


Reproducible: Always
