### Bug fixes

Make the editor scroll while dragging a selection near its sides, even if the cursor isn't outside the scrollable element.

Fix a bug that interrupted composition after widgets in some circumstances on Firefox.

Make sure the last change in a composition has its user event set to `input.type.compose`, even if the `compositionend` event fires before the changes are applied.

Make it possible to remove additional selection ranges by clicking on them with ctrl/cmd held, even if they aren't cursors.

Keep widget buffers between widgets and compositions, since removing them confuses IME on macOS Firefox.

Fix a bug where, for DOM changes that put the selection in the middle of the changed range, the editor incorrectly set its selection state.

Fix a bug where `coordsAtPos` could return a coordinates before the line break when querying a line-wrapped position with a positive `side`.
