Text editor formatting breaks when typing space after backtick in inline code

The text editor has a formatting bug that occurs when typing a space character in a specific position within inline code blocks.

Steps to Reproduce:

1. In the text editor, type the following text:

   Hello `foo` hi `` hello hello

2. Position your cursor immediately after the second backtick (`)

3. Press the space key

Expected Behavior:

The inline code formatting should remain intact and the space should be inserted normally without breaking the markdown rendering.

Actual Behavior:

The formatting breaks when the space is inserted at this position.

Additional Context:

This appears to be related to how the editor handles inline code syntax (backticks) when spaces are inserted at boundary positions between code blocks.
