Webviewer iframe deprecation warning in v10.2

I have read that you plan to deprecate the Webviewer’s iframe constructor in a future release (Apryse Documentation | Documentation). When we did a simple test to replace the iframe constructor with the new Web Component constructor, we noticed some styling impact but also a significant performance impact. So we were wondering when you are planning to deprecate and stop support for the iframe implementation.

I have also noticed that the following error is thrown since @pdftron/webviewer version 10.2:

Refused to apply style from 'http://localhost:4202/lib/ui/style.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

The Webviewer iframe’s index.html still contains a reference to a style.css file, but that file is no longer present in v10.2, resulting in the above error with the iframe view. This error is also thrown with the Web Component view.

Hi, this will be fixed in the next patch release. Sorry for the inconvenience!

Thanks. Do you also have some information regarding when the Webviewer’s iframe support will be deprecated as mentioned on this documentation page: Apryse Documentation | Documentation?
