For almost every interaction we care about, there will be both a top-level `mouseover` and `mouseout` event that occurs. Only use `mouseout` so that we do not extract duplicate events. However, moving the mouse into the browser from outside will not fire a `mouseout` event. In this case, we use the `mouseover` top-leve...

Performs equality by iterating through keys on an object and returning false when any key has values which are not strictly equal between the arguments. Returns true when the values of all keys are strictly equal.

Returns {start, end} where `start` is the character/codepoint index of (anchorNode, anchorOffset) within the textContent of `outerNode`, and `end` is the index of (focusNode, focusOffset). Returns null if you pass in garbage input but we should probably just crash. Exported only for testing.
