[#1]

When attempting to click on the inside vertical slider to scroll through a list of projects from a report, the slider cannot be controlled. Clicking on the slider results in random movement away from the mouse icon. The only way to scroll through the list is by using the mouse wheel. When using only the mouse wheel to scroll through a long list, it takes too much time and effort.

This was using the latest version of Mozilla Firefox version: 86.0

Support didn't seem interested in resolving this.
