### Bug fixes

Fix a crash in `drawSelection` when a measured position falls on a position that doesn't have corresponding screen coordinates.

Work around unhelpful interaction observer behavior that could cause the editor to not notice it was visible.

Give the cursor next to a line-wrapped placeholder a single-line height.

Make sure drop events below the editable element in a fixed-height editor get handled properly.

### New features

Widget decorations can now define custom `coordsAtPos` methods to control the way the editor computes screen positions at or in the widget.
