PR 11732 only fixes the misnaming issue, it doesn't fix the issue where ToolStripTextBox gets the focus and then triggers a refresh of the entire control causing it to lose focus.

Verified the issue on feature/10.0 branch of dotnet/winforms repo that the " extra numbers" issue of ToolStripMenuItem has been fixed, but the issue where ToolStripTextBox gets the focus and then triggers a refresh of the entire control causing it to lose focus still exist.
