bug: Latex injections appear multiple times in AST

Describe the bug

When I edit a markdown file, latex injections appear multiple times in the AST shown by :InspectTree. I'm not sure if this is a bug, but it seems weird and I wanted to report it.

Steps To Reproduce/Bad Parse Tree

1. Have nvim-treesitter plugin with markdown* and latex parsers installed
2. :set ft=markdown

3. paste

   some text
   
   $\alpha = 1$

4. :InspectTree

Result: The inline math is present multiple times in the AST, specifically it is present where the cursor is in the picture below. If there are n paragraphs before the inline math in the markdown file, the inline math is is present n+1 times in the AST.

Additional Info

• Neovim: Tried with 0.9.5 and nightly
• nvim-treesitter 19c6b0c4c9b35962e45b782e2b85a3214d2ac4d5 (2024 Apr 25)

Expected Behavior/Parse Tree

I would expect the inline math to show only once in the AST.

I think this might be an issue with the neovim injection logic, tree-sitter parse gives the correct AST (at least when looking at just the (latex_block) nodes)
