[Bug] PDF++ is not working in embedded PDF in canvas view

[justarmadillo]

Steps to reproduce

When I embed a PDF inside canvas, the plugin features aren't available inside canvas embed, until I open it to the right or something.

Expected behavior

being able to annotate and use the features of PDF++ like inside a note or like when I open it in new window, so I don't need to open each PDF separately in a new window and edit it.

Actual behavior

working Perfectly with in other places in obsidian, not in canvas view embed.

Screen recordings or screenshots (sandbox vault)

only basic PDF.js in canvas embed here, no addon features.

Hi, my apologies for the late response.

When you say it doesn't work in Canvas, it can mean two different things:

1. when you copy a link to text selection in a PDF viewer (either in canvas or not) and paste it into a canvas card, the selected text is not highlighted
2. A markdown file (not a canvas card) has a link pointing to a PDF text selection, and the selected text is not highlighted when the PDF viewer is embedded in a canvas, while it works when you open the PDF in a normal viewer.

Which one do you mean? If it's 1, that is indeed an expected behavior coming from the limitation of the Obsidian core. See the related issue #43.
If it's 2, it seems like a PDF++ bug since you have the "Highlight backlinks in Canvas" option enabled. But at this moment, I can't reproduce it.
