It does under the following conditions:
- Clean start with tabs from previous session with certain pages (for me it is a corona dashboard https://experience.arcgis.com/experience/478220a4c454480e823b17327b2bf1d4)
- If I interact with the page (https://experience.arcgis.com/experience/478220a4c454480e823b17327b2bf1d4) the entire browser freezes
It also happens on other sites but it is freezes/crashes without fail on this page.
Here are two short clips about this issue.
Latest stable version: https://streamable.com/9bbp7r
Latest beta version: https://streamable.com/9nzu4m
As you can see, it crashes on the stable version but not on the beta version.
