@Lewis - Wrapping the width properties in a min-width media query at line 140 in toolbar.module.css doesn't seem to be feasible for viewports < 264px. At this breakpoint toolbar-oriented class is removed, also if we add min-width media query as:
@media screen and (min-width: 320px) {
.toolbar-processed .toolbar-tray-vertical { width: 240px; width: 15rem; }
}
toolbar tray doesn't span 100% width below 264px by default.

Added a new patch for extremely narrow viewports as per #18.
