UseNativeColHeader() results in blank column labels when wxGrid is wider than window (Issue #26014)

jey5nd6 created an issue (wxWidgets/wxWidgets#26014)Description
wxGrid::UseNativeColHeader( true ) results in blank column labels when wxGrid is wider than window.
Potentially MacOS-only.
Ref KiCad bug: https://gitlab.com/kicad/code/kicad/-/issues/18198
To Reproduce:
Add the line:
grid->UseNativeColHeader( true );
after:
grid->CreateGrid( 0, 0 );
in griddemo.cpp. (Should be around line 598.)
Build the sample.
Scroll the grid to the left. Note that newly-exposed columns on the right have blank column headers.

reproduces the problem for me there but not under Windows or Linux (where this exposed another small problem which I fixed, but not this one).
Will try to debug, but as usual with Mac stuff I'm not exactly brimming with confidence...

vadz left a comment (wxWidgets/wxWidgets#26014)Well, I have a fix, see #26016, but, as I suspected I wasn't able to fix the underlying bug in wxOSX, so this fix is just a workaround — but I don't think there are any drawbacks to doing it like this.
