STP rendering

https://www.fisglobal.com/en/products/tripos-connect-to-the-world-of-commerce renders incorrectly on STP Release 152 (Safari 16.0, WebKit 17615.1.2.3), renders correctly in Safari 15.6.1 (17613.3.9.1.16). See attached screen shots.

Thank you for filing this bug. For some reason I can't reproduce it on 253737@main (tip of trunk). It may have been progressed since (will check it out on STP).

I can't repro it on STP 152 either.

[Jon]

Still reproduces for me, even after disabling all my extensions. Here's an archive of the site as I see it. Any other debugging I should do?

I can't reproduce in any versions of the browser on both OS version and on two different hardware.

[Karl Dubost]

So this is interesting. I was not able to reproduce at all. 
And suddenly I can reproduce but this time on Safari Release, and not on STP.
So the opposite. 

This page has a lot of CSP issues. 
and some connections seem to never end, such as monitoring gif of 311 octets taking ~68s to finish loading.

[Karl Dubost]

Jon, can you still reproduce in a recent version of STP?

[Jon]

Yes, it looks the same in STP 159.

[Karl Dubost]

Checking old bugs. 
I can't reproduce on STP 180. 
(Though I could not reproduce before too. So if someone else can try that would be nice)

[Jon]

STP 180 still renders incorrectly while Safari still renders correctly. It's like STP renders most of it vertically, even the content of the top menu. I've tried various combinations of extensions and other settings and nothing makes a difference. I've also verified that multiple machines have the same rendering issue on both Ventura and Sonoma.

rendering on Safari STP 180 + Macbook M2

I think we need to ask someone else than the two of us. Because we are in a circle of can/can not reproduce. :) 

I tested this multiple times on both a MacBook Intel and a MacBook M2. 
on Sonoma 14.0 (public version) and Sonoma (internal version). And I can't reproduce. 

I also made sure to not have external interactions.
1. Have no extensions installed
2. Develop Menu -> Feature Flags -> Reset Feature Flags
3. Erase all cookies and site data

I will ask someone else. :)

rendering in Safari, firefox, chrome

Tested on 

Safari Technology Preview  180           19618.1.1.2
Firefox Nightly            120.0a1       12023.10.16
Google Chrome Canary       120.0.6070.0  6070.0

[Karl Dubost]

Jon,

This is still working for me on STP 183. 
Did you try after doing this:

1. Have no extensions installed
2. Develop Menu -> Feature Flags -> Reset Feature Flags
3. Erase all cookies and site data

Thanks (Specifically the 1 and 2.)

[Karl Dubost]

In one week I will be closing this. As we are not able to reproduce in an out of the box browser.

[Jon]

Yes, it still renders incorrectly after moving aside my current Safari Tech Preview state and disabling all the extensions. System Safari works fine. I can go ahead and close it out.

[Karl Dubost]

This is so weird.
