when I enclose the HtmlEditor in a Window, and set the width to less than its full width, it shows a double arrow at the end, for you to pop open the missing buttons. see attached (hidden buttons). But when enclose it in a ContentPanel, it goes to the last visible button, and does not show the right arrow. see attached (no right arrows). checking the derived html in the debugger shows that all the buttons are still set to visible, except they are outside the container.
what setting is it that triggers the right arrows to be displayed?
