Issue 47630

Tested on Build: 1.9.79

When a table with more than one row is inserted and the height of its header 
row is adjusted to be more than that of the height of the page, the other rows 
disappear. Also, searching for any text which might have been present in the 
other rows produces a very long cursor outside the boundary of the page.

Steps to reproduce: 
1)Start a new Writer document
2)Insert >> Table-with following selections : Columns:5,Rows:5,Headings-
Checked,Repeat Heading-Checked for The First 1 rows,don’t split table-
Unchecked,Border-Checked.
3)In cell 1x1, type “Headingâ€.
4)In any other cell not in the first row, type “Helloâ€.
5)Right click on any cell in the first row and Select Row >> Height.
6)In the Row Height dialog, enter the height as “38â€, click OK.
7)The other cells disappear – this may be acceptable behavior since there is 
no space on a page for any other rows.
8)Now go to the start of the document and bring up the Find dialog (CTRL+F).
9)Search for the text “Helloâ€, click Find, and click close.
10)Using the mouse, scroll down the document.
11)Notice the very long cursor.
12)Now start typing some text.
13)Notice that the cursor is between two pages and allows typing there, though 
no text can be seen.
14)The cursor stays in the same place on typing or pressing enter, but can be 
moved back inside the table by using the mouse.

Expected behavior:
Writer should not let a user increase the height of the header row beyond the 
height of the page.

Observed behavior:
The height of the header row can be increased beyond the height of the page – 
this results in the other rows becoming invisible and some unconventional 
cursor behavior is exhibited.
