Description:
If a split screen is initialized from another application, window dimensions are incorrectly offset in the y-axis. In this edge case, Mac users cannot precisely use the mouse to select features/cells within the split-view window. This bug is causing users to vertically offset their mouse pointer to interact with the correct objects in the split-view frame.

Steps to Reproduce:
1. On macOS, open a Calc Spreadsheet.
2. Open another arbitrary application other than LibreOffice.
3. In the second application, Hover over the "Full-Screen" button, a green button in the upper left, and you will see options to "Enter Full Screen," "Tile Window to Left of Screen," or "Tile Window to Right of Screen."
4. Select "Tile Window to Left of Screen" or "Tile Window to Right of Screen." 
5. MacOS's Mission Contol will give you options for other open applications to fill the opposite side of the screen. Choose the window of Spreadsheet in Calc.  
6. Select any arbitrary cell or feature in the Spreadsheet in Calc with your mouse. 


Actual Results:
1. The Dimensions of the Window don't fill the entire y-axis of the screen.
2. Users cannot precisely select a particular cell in Calc. - I try to edit the C5 cell, but C3 is selected for editing. This offset continues across the entire application window e.g. User needs to press G16 to access G14. 

Expected Results:
The window for the Calc frame needs to fully scale in the y-axis while in split-view process initiated by another application. 


Reproducible: Always


User Profile Reset: Yes

Additional Info:
The edge case where a Mac User enters split-view from the Calc application works fine.
