When using custom inline styles in BlockNote, an issues arises that makes editing difficult:

• Pressing Enter just before or inside styled text creates a new block as intended, but the cursor remains in the original block, making it difficult to continue editing smoothly.

These issues only appear when applying custom inline styles via styleSpecs — default styles like bold or textColor behave correctly.

To Reproduce

1. Visit the custom inline style docs page: https://www.blocknotejs.org/docs/custom-schemas/custom-styles
2. Set your cursor within the "Comic Sans MS" text, say just after the word "Sans"
3. Click "Enter" -- observe new lines being created, but the cursor remains in the original block at the beginning of the line.
4. Start typing and you'll see the new text appear in the original block, not the newly created block where expected.
