Hi - When prototyping - I would expect to see a mode switch individual components not the global container: for example:
I use Default (no hover) and Hover for Modes - which effects the colors of the text, bg, etc
When I go to create my prototype and I select Hover - set variable mode to: Hover
I expect when I hover over each individual to turn off or on when I hover over them specifically (one at a time) but currently this looks at the whole side rail container and hovers them on all togher
