10 years ago someone asked a question about how Google Chrome was able to show PDFs while they were loading: How chrome showing pdf even not fully downloaded?

However I have noticed that this is no longer true, if you attempt to view a linearized PDF in Google Chrome using the default PDF viewer, you have to wait for the whole PDF to be transferred before it will show you the first page, e.g. https://s3.amazonaws.com/visually-alexey-test/oversize_pdf_test_0.pdf

When was this feature dropped, and why? Or is this likely a bug?
