 // TODO: Make the component customizable by adding custom attributes:

+// FIXME: If the switch is toggled too quickly, the switches in other open tabs may not update consistently.
+//  Steps to reproduce the bug:
+//  - Open two tabs
+//  - Set the theme of both tabs to "auto"
+//  - In one of the pages, click the switch three times in rapid succession so its new state is "auto" again
+//    The other tab should also show auto icon but it shows light icon.
+//  To resolve this, instead of listening for localstorage events, maybe we can pull the
+//  localstorage state for changes every 100 ms and update the switch if necessary.
