I have a customized mapping application originally built with API v 4.17. I am updating to 4.29. Doing so has caused all of my icons in any Expand widget to shift with some form of padding. The padding can be identified with the browser tools as residing in the shadow-root. And no amount of CSS edits seem to be able to adjust the padding. I would be content to just force the padding to 0px but I'm not even sure why it's an issue at all. Even adding a brand new simple Expand widget using the 4.29 tutorial results in a (basemap) icon that is shifted and obscured. Why might this be happening and - as a last resort - how might I edit the styling in the shadow-root to force the fix? See attached images.
