Warning about over 5000 symbols shown even when yaml.maxItemsComputed is MUCH higher

Describe the bug

I have yaml.maxItemsComputed configured to 100000 in my user settings and 500000 in my .code-workspace settings, and yet when I open a large yaml file in my workspace (an OAS spec FWIW), I still get a toast that document symbols have been limited to 5000.

The large file in question is just under 500000 bytes, so it can't possibly have more than 500k symbols.

I was hoping there might be some informative output in the YAML Support output view, but it is completely empty.

Expected Behavior

The setting should be obeyed.

Current Behavior

A warning toast is shown. It is not immediately clear to me if document symbols have actually been limited however, or if the toast is a false positive.

Steps to Reproduce

1. Create a multi-project .code-workspace
2. Change settings as noted above
3. Open a large yaml file

Environment

• Windows
• Mac
• Linux
• other (please specify)

Reproduce the warning with the stated user and multi-project workspace settings on Linux, then inspect the document-symbol limit handling and the YAML Support output behavior. Done means the configured limit is respected and the warning is not shown falsely; no source file or test is named in the issue.
