+++ This bug was initially created as a clone of Bug #1459905 +++
[Spinning this off of Bug 1459905, which had a reduced testcase & a patch land to address that testcase, but apparently the original STR/URL is still broken.]

[Steps to reproduce]:

  1. Launch Firefox.
  2. Visit
  3. Click on the left "<" and right buttons ">", below the "Show Demos Known to Fail" text.

[Expected result]:

  • The photo is moved accordingly.

[Actual result]:

  • Nothing happens when clicking on the right and left buttons.
Summary: Left and right arrow navigation doesn't work if the SVG is rendered with browser native svg → Left and right arrow navigation still doesn't work on photo grid demo at

Actually, the "up" and "down" buttons (^/v) on this site also seem to have no effect in current Nightly, too (whereas those ones were fine in Nightly 2020-08-25).

That feels unexpected, and it could indicate that bug 1459905's patch somehow took us a step away from correctness (at least as far as this demo is concerned).

Robert, perhaps you could take a look / do you know why the behavior might've changed in this way?

If you zoom first then everything suddenly starts to work so I really don't know what's going on with the site.

We're not reacting properly to the dynamic change of currentTranslate. But the change is reflected in the JS objects.

I can poke.

Hi guys,

So I checked this bug on Windows 10 on Nightly 82.0a1 (2020-08-31) (64-bit) and it's been fixed.

Regards, Flor.
