Issue

We applied the settings indicated in the article Document that is downloaded instead of previewed in the browser for MHTML files, but it still does not work as expected.

Environment

Liferay DXP 7.0+
Liferay PaaS

Resolution

The content-disposition property used to inform how the content will be rendered is as expected after adding the property mime.types.content.disposition.inline in the portal-ext.properties, with the value inline.
However, even with this property, the browser does not render the content, unfortunately.
This is a browser issue, not related to our source code, it is how browsers work.
