Description

Formats (bold, italic, link) don't seem to be supported in content (the inner html of an element) using the block bindings API.

Step-by-step reproduction instructions

Prerequisite: Enable the pattern overrides experiment from the gutenberg experiment page.

• Create a new post
• Insert a mixture of blocks that include paragraphs and optionally other blocks too
• Select the blocks, and 'Create a pattern' from the block options menu
• Give the pattern a name and make it 'synced'
• Click the 'Edit original' button on the toolbar
• Select a paragraph block in the pattern, and in the block settings sidebar expand the advanced section. Check the 'Allow instance overrides' option
• Use the 'Back' button in the header area of the editor to go back to the post
• Edit the paragraph and add formats
• View the post on the frontend

Expected: The frontend should show the added formats as normal
Actual: The html of the formats is shown
