Facebook modal bug

One sec causes modals to not close on facebook.com until the exit button (which functionally seems to work like a back button) has been clicked enough that it returns to a different web page. Bug seems to occur for all modals (clicking on Facebook Marketplace listings, video posts, image posts etc.) and occurs even if website is not added on the extension. Bug linked to one sec extension by disabling extension and verifying that bug no longer occurs. Occurs for Microsoft Edge seemingly as of the latest 1.40 updated, have not tested for it on other browsers.
