Using the "chassis-b" sample from the 6.5 SDK ("vsphere-client-sdk-6.5.0-4602587.zip"), the "Configure" and "Monitor" tab extensions have double scrollbars - see attached screenshot. This is easily reproducible by just adding extra content to one of the sample HTML pages (I've attached a suitably-modified sample as well). This effect occurs in the latest versions of both Edge and Chrome.
Using in-browser debugging tools, it appears that the extra outer scrollbar, which only allows scrolling by a few pixels up and down, is on <div vx-view class="vui-tab-content">, and the inner scrollbar is on the <iframe> element. There are three nested <div class="fill-parent"> between the two.
As all of these elements are outside of our plugin, our HTML/style sheets have no control over them, and there seems to be no way for us to fix this behaviour.
Is this a known issue? Is there any fix/workaround both for development and production?
