Inserter

Continues the work done in previous releases around balancing writing flow with the ability to easily insert non-text blocks.

• Show the full block inserter (+ button) to the left of empty paragraphs and the default appender. Quick block options (based on compound frequency and recency) remain on the right.
• Insert default block as provisional — this reduces the proliferation of empty blocks as the editor removes these provisional blocks when unfocusing.
• When pressing enter from post title, insert initial block as provisional.
• Fade out the side inserter when typing on the newly created block.
• Group common block definition on inserters. Use 'frecency' to sort items on top of it.
• Improve the visual focus style for inbetween inserter.

Writing Flow

Strengthened, tweaked, and polished underlying mechanisms for handling the writing flow in order to provide more stability and consolidation.

• Move isTyping behaviour to a separate component.
  
• Inserting a block should only shift focus to a text field, otherwise focusing the block's "focus stop".
  • Example: Inserting an image should focus the top-level placeholder.
• Pressing backspace or enter from the block's focus stop should respectively delete or insert a subsequent paragraph block.
  • Example: Pressing enter or delete on an image placeholder.
• Pressing down arrow from a non-text-field should proceed with a tab transition as expected.
  
• Multi-selection at the last text field in a block now accounts for non-contenteditable text fields.
• Better internal identification of text fields for writing flow transitions. Previously, if a block contained a checkbox, radio, or other non-text input tags, they would be erroneously included in the writing flow sequence.
• Inserting paragraph block (quote, etc; those with text fields) via autocomplete should move focus to the cursor.
• Shift-arrow from a text field engages multi-selection, but not if there are other text fields in the intended direction in the same block.
• Cancel isTyping state when focusing non text field.
• Improve reliability of the block click-to-clear behavior.
• When clicking below the editor move focus to last text field — this includes creating a new provisional block if last block is not text. This is equivalent to the default block appender spanning the entire viewport height of the editable canvas.
• Introduce same undo buffering for general text to the post title (and other post properties).
• Allow breaking out of List block upon Enter on last empty line.
• Address conflicts between WritingFlow's selection transitioning and nested blocks by moving selection to the block's focus handler.
