math editor line wrap

How can one change the column (number of characters) at which the Math Commands editor window uses to wrap lines? For example, when I edit the formula

A = left [ matrix {   
  1 # 0 # 0 # 0 # 0 
A_{2,1} # A_{2,2} # A_{2,3} # A_{2,4} # A_{2,5} 

the Commands window wraps the second row of the matrix at

A_{2,1} # A_{2,2} # A_{2,3} # A_{2,4} 
# A_{2,5} 

when what I really want to do is to make the window bigger to see the matrix row on one line of text.

I guess I should post my version/environment:

Version: (x64)
Build ID: 747b5d0ebf89f41c860ec2a39efd7cb15b54f2d8
CPU threads: 16; OS: Windows 10.0 Build 18363; UI render: default; VCL: win;
Locale: en-US (en_US); UI-Language: en-US
Calc: threaded

Same LO version, Fedora Linux, but can’t reproduce behaviour. Anyway, the most important thing is taht the formula is correct in Writer. I admit it is inconvenient to have matrix rows unsynchronised (single line/multiple lines) when editing.

well, that narrows it down. Is it specific to MS Windows, or my particular install? Any Windows users out there?

So on one Win10 computer with LO, Math Commands window (undocked, floating) wraps at character 38, regardless of Commands window size.

On a different Win10 computer with LO, the line wrap happens at character 72, either docked or floating. (Although I don’t see how to return the floating Commands window back to docked). Updating that ‘different’ laptop to, it now wraps at 63 characters.

Also, there is a bit of a bug where the command window doesn’t set the window focus properly when sizing from narrow to wide. For example, if only characters from 50-63 are visible in a smaller window and the cursor is on character 55, the window doesn’t pull in characters <50 when enlarging, even though the horizontal scroll bar indicates that the full width should be visible.
