Syntax highlighting and checking often breaks while typing comments

Describe the bug
When I type comments into Java code, the syntax checking and highlighting sometimes gets out-of-sync for code below the comment insertion point.

To Reproduce
Steps to reproduce the behavior:

1. Type a comment
2. Observe that the syntax highlighting breaks
3. After waiting a second, type one more character, and observe that it fixes itself

This appears to happen for all projects for me, so I don't think a minimal reproducible example is possible. I don't even know where to start with making a minimal example.

Expected behavior
Syntax highlighting consistently and immediately updates as I type.

Environment

• Operating System: NixOS 25.11, but have also reproduced on Fedora Linux
• JDK version: 21
• Visual Studio Code version: 1.113.0
• Java extension version: 1.53.0

Il report non indica file sorgente, test o punti di ingresso. Inizia riproducendo l’aggiornamento ritardato dei commenti nella VS Code Java extension con le versioni di JDK e dell’editor indicate, quindi segui il percorso del controllo e dell’evidenziazione della sintassi incrementali; il lavoro è completato quando gli aggiornamenti rimangono immediati e coerenti mentre si digitano commenti.
