1788833 - PDF Viewer Shortcuts Not Working With Certain Parameters

Status: RESOLVED DUPLICATE of bug 1787456

(Firefox :: PDF Viewer, defect)

Description

[ml]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:104.0) Gecko/20100101 Firefox/104.0

Steps to reproduce:

Shortly after updating to 104.0.1, I opened a PDF in Presentation Mode using the shortcut in the top right corner of the PDF viewer. (The PDF in question is a copy of Hermann Neuling's Bagatelle for Horn and Piano, but I replicated it with other PDFs after the fact.) I tried to scroll between pages with the arrow keys on my keyboard (left/right), but they did nothing--the only keyboard shortcut that worked was pressing Escape. Restarting Firefox/reloading the PDF in question did not help, and I was unable to scroll between pages using keyboard shortcuts, nor was I able to with other PDF files.

However, if I open Presentation Mode with a keyboard shortcut (Control + Alt + P), I can freely scroll between pages with the arrow keys on my keyboard like I normally would be able to. If I close Presentation Mode afterwards and try to open it again using the shortcut in the top right corner, the problem persists.

This is so hilariously specific that I have to assume it's a bug.

Actual results:

I wasn't able to scroll between pages in Presentation Mode with the PDF viewer using my keyboard when using the shortcut in the top right corner of the PDF viewer to open Presentation Mode. Instead, I had to open Presentation Mode using the keyboard shortcut (Control + Alt + P), where keyboard shortcuts worked fine.

Expected results:

I should have been able to scroll between pages in Presentation Mode with the PDF viewer using my keyboard when using the shortcut in the top right corner of the PDF viewer to open Presentation Mode.
