Description:
There is a "x" near the top right-hand corner of the screen when one document is open in LibreOffice. The role of this "x" is to close the document when it is clicked with a mouse. However, the "x" disappears when one or more documents are open. It would be logical for the "x" to remain, so it is available to close an individual document, especially when multiple documents are open. 

This "x" is just below the larger "X" that is nearer to in the top right-hand corner, which closes LibreOffice, so please do not confuse the small "x" with the larger "X".  At least, these are the sizes on my screen.

I think this also affects LibreOffice spreadsheets and Draw too.

Steps to Reproduce:
1. Open a text document with LibreOffice. Look for the "x" near the upper right-hand corner. You can use it to close the document to text its functionality.
2. Re-open a text documents with LibreOffice. The  open another document (writer, calc, or draw). The small "x" disappears.
3. You have to use a drop-down menu to close the the document in the view, but the tendency is to look for the "x" in the top right-hand corner, but it has gone.

Actual Results:
as above

Expected Results:
It would be logical for the "x" to be available to close the document in the view.

Additional Info:
I have been aware of this inconsistency for a long time, and think that is time for it to be fixed.

I have entered it as a fault of the latest version of the master 24.8, which I downloaded today; however, the issue has been present for a long time.
