[Bug 1962580] Re: Blocktype PDF - Missing command icons on PDF viewer
Hi Alex,
Thanks for reporting this.
I can confirm that the issue appears when using Safari, i.e. the icons
of the PDF viewer are not displayed.
Further details:
- When testing the PDF Viewer with Safari on master-dev-testing, which has the latest PDF.js upgrade included, there is also an error in the viewer and it won't display the PDF:
"An error occurred while loading the PDF.
PDF.js v2.14.2 (build: 2cc98dcda)
Message: Can't find the variable: structuredClone"
There are no errors when using the PDF viewer with master-dev-testing on
Chromium or Firefox.

Title:
Blocktype PDF - Missing command icons on PDF viewer
Status in Mahara:
New
Bug description:
Our Mahara 21.10 installation is on an Ubuntu 20.10 LTS Server running
PHP 7.4.
Using Safari in a view containing a PDF block the command button icons
of the PDF viewer are not displayed (Buttons are graphically "empty").
Nevertheless normal functionality is provided by clicking on those
buttons.
This issue doesn't appear on Firefox and Chrome. Looking at the
console output it shows, that in Safari the icon svg files are fetched
from a different location on the server than in Firefox and Chrome.
Does anybody else has this issue?
Cheers
Alex
