Bug 259093 – REGRESSION (Safari 16.3): Passing "noopener" as third argument opens tabs into new window

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKit Misc.

[Erica]

Given MDN documentation and prior behavior, the following function call shall open in a "new tab" if the browser setting is set to "automatically"
 
window.open(path, "_blank", "noopener=true"); 

Per MDN: "Note: Specifying any features in the windowFeatures parameter, other than noopener or noreferrer, also has the effect of requesting a popup."
"If popup is not enabled, and there are no window features declared, the new browsing context will be a tab."

Given this, the expectation is the above line of code should open in new tab. However it is opening in a new window. This is reproducible across multiple user environments.

Thank you for the report! Could you please clarify which versions of Safari this worked in, and which work incorrectly?

[Erica]

Thanks for triaging this, the version of current not working version of safari is Version 16.3 (18614.4.6.1.5). Per our product manager, this was previously working for him on Version 16.2 (18614.3.7.1.5). Thank you!
