Popup - parent element not found

When trying to get the data from a popup, I get 'parent element not found.

I can replicate the issue on websummit for example, see the example sitemap:

Url: Meet the startups that joined us at Web Summit 2022

Sitemap:
{"_id":"websummit-2022","startUrl":["https://websummit.com/startups/featured-startups"],"selectors":[{"id":"selector","parentSelectors":["_root"],"type":"SelectorElement","selector":"a.MuiPaper-root","multiple":true},{"id":"clicker","parentSelectors":["selector"],"type":"SelectorElementClick","clickElementSelector":"_parent_","clickElementUniquenessType":"uniqueText","clickType":"clickOnce","delay":500,"discardInitialElements":"do-not-discard","multiple":true,"selector":"html"}]}

When trying to create a selector under clicker, it does not work and is not clear to me why.

Edit:
The issue seems to exist when the parent is in a different part than the opening popup, looks like there's no way around this.

When you click on the first company, all the rest of the companies' info are also loaded into the carousel (the popup), so it is not hard to scrape. It looks like 48 companies per page. You just need a paginator to complete this:

{"_id":"websummit-2022","startUrl":["https://websummit.com/startups/featured-startups"],"selectors":[{"clickActionType":"real","clickElementSelector":"div.MuiGrid-align-content-xs-flex-start > div > div:first-of-type > a","clickElementUniquenessType":"uniqueText","clickType":"clickOnce","delay":2000,"discardInitialElements":"do-not-discard","id":"Click first company","multiple":false,"parentSelectors":["_root"],"selector":"div.MuiGrid-align-content-xs-flex-start","type":"SelectorElementClick"},{"id":"Company popup elements","multiple":true,"parentSelectors":["_root"],"selector":"ul[class^='sliderTray_'] > div[class^='jss'][style]","type":"SelectorElement"},{"id":"Company","multiple":false,"parentSelectors":["Company popup elements"],"regex":"","selector":"div > h1","type":"SelectorText"},{"id":"Desc","multiple":false,"parentSelectors":["Company popup elements"],"regex":"","selector":"div > div > p","type":"SelectorText"},{"extractAttribute":"href","id":"Website","multiple":false,"parentSelectors":["Company popup elements"],"selector":"div > div > a:first-of-type","type":"SelectorElementAttribute"},{"id":"Country","multiple":false,"parentSelectors":["Company popup elements"],"regex":"","selector":"div > span > svg+span","type":"SelectorText"}]}
