Describe the bug
When I try to open a ui5-responsive-popover with two ui5-list as children, I get the following error:

List.js:595 Uncaught TypeError: Cannot read property 'id' of null
    at HTMLElement.isForwardElement (List.js:595)
    at HTMLElement._onfocusin (List.js:561)
    at EventPart.handleEvent (parts.ts:512)
    at HTMLDivElement.EventPart.__boundHandleEvent (parts.ts:470)
    at HTMLElement.applyFocus (Popup.js:290)
    at async HTMLElement.applyInitialFocus (Popup.js:274)

Hello @ui5-webcomponents-topic-p I am forwarding this issue to you, because the "isForwardElement" methodof the List is not working properly in some cases.

Best regards,
Martin

hello colleagues, thank you for the quick fix on this issue! Is there any ETA on when it will be released? This is currently blocking our production release in our app

[ilhan007]

Hello @stevetsanders can you share more details about your app and release plan?
Our release plan can be seen here https://github.com/SAP/ui5-webcomponents/projects

The next RC will be released on 11 Feb. But, there is an option to provide you a "master" version, that includes the very latest development. The version would look like 0.0.0-commit_id and can be installed with the "next" tag

npm install @ui5/webcomponents@next

Hi @ilhan007 , Actually I spoke wrongly. It doesn't impact our production release, but we did want to update our libraries with a couple of new features available.

Thanks a lot for the info, I'll try to install the version for the specific commit and see if it works out.

UPDATE: I guess the next version is not yet updated for the latest commit. Is this something you must trigger manually?

[stevetsanders]

hi @ilhan007 , any chance you could provide another 'next' version so we could try it out?
