Description of the issue:
Scrolling using Keyboard in URLs with PDF extension do not work. Can’t use PgUp, PgDn, can’t use up-arrow, down-arrow. I can only scroll using the mouse wheel or scroll bar. On any other web page, like with a HTML extension, the keyboard works as it should.
How can this issue be reproduced?
Go to any URL with a PDF extension. For example, https://www.skybrary.aero/bookshelf/books/262.pdf
Try and use any keyboard key to advance in the PDF.
That I be able to scroll using the keyboard like any other web page.
Brave Version( check
EL CAPITAN. Not upgrading due to aged hardware. If El Capitan is the issue and Brave won’t play nice with it, then you shouldn’t allow it to be installed on El Capitan.
NO EXTENSIONS ENABLED. Nothing could be causing this other than Brave.
