SVG+XML images with data URIs that render only in Chrome/ium

Post by moonbat » 2019-11-11, 03:36

This page doesn't display images even in safe mode, nor does it work in Firefox. To no surprise, only Chromium displays it. 'Living standard' strikes again?

Images in question have URLs like this -

Code: Select all

data:image/svg+xml,%3Csvg%20xmlns='http://www.w3.org/2000/svg'%20viewBox='0%200%201000%20600'%3E%3C/svg%3E
The link above only shows an XML namespace for SVG. What sorcery is this? :wtf:
If it's a data URI then where's the image data getting loaded from?

Mine looks like this:

Seems all the pics are there for me on the whole page. The one blank space was a YT vid which I made appear by allowing in nMatrix.

I'm not a programmer and have no idea what you're talking about. All I know is everything on the site seems to be working as it should. Maybe my system's hosed up (or down).

Unblocking cookies for the site fixed it.

Interesting. I have cookies blocked for the site without ill effect. I don't use the cookie blocking utilities you do, though. Only nMatrix.

The SVG is a placeholder image frame (defining a viewport) for lazy-loaded jpgs that are slid in with js after the document is loaded... because, ... Wordpress, I guess.

Off-topic:
Just because cookies are blocked in nMatrix doesn't mean they are blocked in the browser.

nMatrix doesn't block a site from sending you cookies; that's controlled by your browser settings (with or without the aid of a cookie management extension, which nMatrix isn't). The effect of blocking cookies in nMatrix is to prevent them from being sent back. (see wiki)

Thanks for the information! I've always had it set to delete blocked cookies automatically. I see that the contents of that wiki are behind the ? button next to the setting in the dashboard, but had been using the old uMatrix that was compatible with PM until recently and that description wasn't there AFAIR. I'm still satisfied with how that works. Thanks again!

The information is there, in the same place, in PM-compatible versions of uMatrix, though it might not have registered when you first read it. :)

Apparently, it didn't. Thanks again for the clarification. :)

The scrollbar on that page is weird as well. It has its own appearance, and appears only when the cursor is moved to that side of the page.
