Able to reproduce the issue on Windows, Mac and Linux. Changing the status to Untriaged so that the issue could get addressed.
Thank You.

Jennifer, it seems we should be disabling the default context menu in the MR overlays. WDYT?

SGTM.

takumif@: I saw your CL for this go out. There was an offline chat about just disabling "Print" in the contextual menu rather than the entire menu after #5, and we never updated the bug to reflect it.

Can you confirm with skonig@ about our intended behavior here? Thanks!

I don't see any harm in having a contextual menu, so long as the options are valid/make sense/work.  If we've disabled Print already and everything else is fine to have there, I'm good with where we've landed.

Actually, we haven't disabled Print yet. Jennifer was working on it sometime ago but she never submitted it, and now she can't find it anymore. I agree that just disabling Print would be good, unless it's really complex to do so.

SGTM on disabling Print. I can show you what files I was working on if you need any pointers, just let me know.

Disable Print in the context menu when a modal dialog is shown

Disable the "Print..." option in the page context menu when chrome::CanPrint
is false. This disables printing when a modal dialog, such as the Media Router
dialog, is being shown, just like the Print option in the hotdog menu.

Revert of Disable Print in the context menu when a modal dialog is shown (patchset #3 id:40001 of https://codereview.chromium.org/2215123002/ )

Reason for revert:
chrome::FindBrowserWithWebContents(source_web_contents_) returns a nullptr for the PDF viewer, causing the Print option to be disabled for PDFs. We need to replace chrome::FindBrowserWithWebContents(source_web_contents_).
