Created attachment 182568 [details]
A generated DOCX with MHT altChunk

The attachment is from https://ask.libreoffice.org/t/ms-word-document-opens-as-blank-in-lo-writer/82009. It opens OK in MS Word, having four pages with content; but opens blank in Writer.

The DOCX contains an MHT sub-document, referenced from word/document.xml using altChunk element.

Repro with

Version: / LibreOffice Community
Build ID: 35702fd6781542f5eefbd3710304ab9a25ac61fe
CPU threads: 16; OS: Linux 5.15; UI render: default; VCL: kf5 (cairo+xcb)
Locale: pt-BR (pt_BR.UTF-8); UI: en-US
Calc: CL threaded

Indeed the file opens blank in LO Writer. However in MSO it indeed has contents.

As long as LibreOffice cannot render such format, it should show an info to the user.
