You can test if the current buffer shows *Help* and change
`w32-grab-focus-on-raise' only in that case.

I think we have established that "this bug" is not a bug.  So please
refrain from calling it a bug.

I don't understand what you mean here.

`w32-grab-focus-on-raise' is a variable, not an option.  IIUC it is a
workaround that might work in some cases.  Apparently, it can fail in
other cases.

> Would you please make this change to `help-window-setup'?

It would require further tuning.  In its current form it would focus a
frame that already has focus which is a bad idea.
