Major Description
Originally noticied in Cristal app on Nextcloud instance editing a bit large document. But it also can be found in XWiki Jetty/HSQLDB 18.9.0 instance with installed and selected Blocknote as editor.
When inserting a link through the /link quick action on a large page (ex. Sandbox), the editor unexpectedly scrolls to the bottom of the page with opened link dialog instead of keeping the user's current position. This behaviour doesn't happen if user inserts code block or other element into page.
