[orca-list] Invisible objects on web sites

[Vojtech šmiro <vsmiro seznam cz>]

Hello,

At this page
https://www.toprecepty.cz/recept/3836-stepanska-hovezi-pecene/
are invisible objects. I've tested this website with Chromevox in 
Cloudready and it worked perfectly. In linux in Firefox the objects are 
invisible.

Steps to reproduce
1. At the page press H to heading level 2, Suroviny. If you press down 
arrow three times, it jumps to Naše kuchařky právě v prodeji heading 
level 2 and you can't find what you need to cook this dinner. In 
Chromevox or Blindshell Classic 2 phone, there are checkboxes with 
things you need.
2. The next bug: go to heading level 2 Postup přípravy and read by down 
arrow. You have steps to cook 1, 2, 3, but the steps are invisible with 
Orca.

I've tried it with Orca Master in Ubuntu or in Debian. Is some way to 
repair it? If not, never mind, I will work with that on Chrome or 
Blindshell.

Thanks a lot.

Best regards

Vojta.
