The annotation selection cannot be discarded once at least a single character got selected ⚠️

[oleksandr-danylchenko]

Issue

Once you start selecting the text either by mouse or keyboard, you cannot cancel it by collapsing the selection range.

Mouse

selection_loop.mp4

The mouse selection dispatches the selectstart event only once and after that, only the selectionchange until you release. During that time you're stuck in "at least 1-char selection limbo", and the rendered highlight won't get dismissed

Keyboard

keyboard_selection_loop.mp4

The keyboard selection dispatches the distinct selectstart event each time the previous selection range becomes collapsed. So each time you switch the selection direction, a new leftover annotation gets saved. Which is even more annoying than the mouse-limbo 💀

Suggested Changes

We should track the moment when the previously populated selection range collapses. That should signify the selection cancellation. Then, such leftover annotations can be deleted.
