 It's also possible, but dangerous, to mix class and classList. The main safe situation is when class is set to a static string (or nothing), and classList is reactive. (class could also be set to a static computed value as in `class={baseClass()}`, but then it should appear before any classList pseudo-attributes.) If both class and classList are reactive, you can get unexpected behavior: when the class value changes, Solid sets the entire class attribute, so will overwrite any toggles made by classList.
