No syntax highlighting for in-product release notes code blocks.

[gregvanl]

• VSCode Version: 1.25 Insiders
• OS Version: Windows 10

Steps to Reproduce:

1. Help > Release Notes
2. Look for json or TypeScript code blocks

Code blocks are simply white on black (default dark theme) with no syntax highlighting.

Seems to only happen on the first time. If you close the release notes and try again, the code blocks are correctly highlighted.

No such console output on second try when there is syntax highlighting.

I wonder if this could be due to change to delay load TextMate grammars 54ff9a1#diff-7d43e3fab25f026e232da23df0f2139c @aeschli

@mjbvz I still see this issue for in-product release notes. Just saw it for 1.25 Stable update. Shall I reopen this issue or create a new one?

[aeschli]

The output No grammar found for scope source.applescript is caused by changes by my change and is just for info. We should track this in a separate issue. I created #53860

[mjbvz]

@aeschli Do you think we will have a chance to look into this early next week?

This seems to be fixed in 1.26.0
