[BUG] Quote shortcode '>' only works if quotePlugin is initialized before markdownShortcutPlugin()

• I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
• [ x I have read the documentation and cannot find an answer.

Describe the bug
If the quotePlugin() is initialized after the markdownShortcutPlugin(), the quote shortcode > does not work. If the quotePlugin() is initialized before the markdownShortcutPlugin() it does work.

Reproduction
Link to CodeSandbox

To Reproduce
Steps to reproduce the behavior:

1. Open the CodeSandbox link
2. Try to activate the quote block by typing '>' followed by a space on a new line.

Expected behavior

1. The qoute block shortcode should work regardless of the initialization sequence of the markdownShortcutPlugin and the quotePlugin
2. or an error should be thrown, informing the user of the correct order of initialization.

Desktop (please complete the following information):

• OS: tested on Windows
• Browser: Chrome

Additional context
Thank you for the great work on this editor!

Start by reproducing the issue from the linked CodeSandbox and trace the interaction between quotePlugin() and markdownShortcutPlugin(). Verify the initialization-order behavior, then make the quote block shortcode work in either order or confirm that an explicit initialization error is required.
