Quarto vignette titles are broken with quarto 1.6.x

[banfai]

With the pre-release version of quarto the page title has a glitch, it's in a different div <header id="title-block-header" class="quarto-title-block">) instead of the previous <div class="page-header">. This causes the Source link to be placed above the title:

release version on gh-pages:

same version rendered with quarto 1.6.37:

The page-header div is still there with the logo and the source code link, but the title is missing: <h1></h1>

quarto::quarto_version()
#> [1] '1.6.37'

It remains the same with specifying

format:
  html:
    title-block-style: none

I believe it's caused by this:
quarto-dev/quarto-cli#10567
quarto-dev/quarto-cli#11224

Quarto tests are also failing with the new release, this appears to be the same problem:

Failure (test-build-quarto-articles.R:59:3): auto-adjusts heading levels
xpath_text(html, "//h1") (`actual`) not equal to "title" (`expected`).

`actual`:   "" "title"
`expected`:    "title"

Failure (test-build-quarto-articles.R:104:3): quarto headings get anchors
xpath_attr(headings, "./a", "href") (`actual`) not equal to c("#heading-1", "#heading-2") (`expected`).

`actual`:   "#heading-1"             
`expected`: "#heading-1" "#heading-2"
