Table: Virtual Scroll with Subheader

[garysb]

Describe the bug

I am using virtual scroll lazy with the given sub-header template.
sub-header
virtual scroll lazy

My subheaders disappear when I add lazy loading logic to the table.

	"dependencies": {
		"@angular/animations": "19.1",
		"@angular/common": "19.1",
		"@angular/compiler": "19.1",
		"@angular/core": "19.1",
		"@angular/forms": "19.1",
		"@angular/platform-browser": "19.1",
		"@angular/platform-browser-dynamic": "19.1",
		"@angular/router": "19.1",
		"@primeng/themes": "19.0",
		"primeicons": "7.0",
		"primeng": "19.0",
		"tailwindcss-primeui": "0.4",
	},

This issue has been mentioned multiple times before eg. #15104 opened last month by @mirinio which I am guessing was closed due to not relating to the latest version?

Additional notes: your stackblitz template is broken. (An unhandled exception occurred: Cannot find package 'vite' imported from...)
