The annotation selection cannot be discarded once at least a single character got selected ⚠️ #139
Description
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.
