fix: demo page representation selector

[adrums86]

Description

The VHS demo page representation selector was not allowing the user to select the first or 0 indexed representation in the list.

Specific Changes proposed

Remove the !selectedIndex check and change the expected index to < 0 for "no element selected". See: https://developer.mozilla.org/en-US/docs/Web/API/HTMLSelectElement/selectedIndex
