1801570 - Changing image source to empty data url still renders old image

Status: UNCONFIRMED

(Core :: DOM: Core & HTML, defect)

Description

[Justin Peter]

(Apologies if this isn't the right component; I'm not entirely sure here.)

When navigating to a page with <link rel="icon" href="data:;base64,=">, the tab bar renders the favicon of the previous page. When opening in a new tab, it correctly recognizes that the page does not have a valid favicon.

STR:

1. Go to https://news.ycombinator.com/item?id=33683571
2. Click on the link "Welcome to the First RISC-V Site" at the top of the page
3. Notice that the favicon does not change

Mozregression points to bug 1718220; prior to this, no favicon was rendered.

(A slightly related question: this page sometimes renders the icon for no favicon, but others, such as example.com, simply do not render a favicon. Is this intentionally inconsistent?)

Attachment: Test-case.

This seems like a more general problem with <img>...

Doesn't seem like a recent regression...
