problem with "Share" tab when Atlascope is loaded in an iframe in Chrome/Chromium browsers

[itspangler]

in Google Chrome, the share button (e.g

atlascope-v2/src/lib/mapControls/ShareControls.svelte

Line 25 in 8a8b3c6

function copyURL() {

) does not work when Atlascope is embedded as an iframe. see Amy Finstein's article for reference

clicking the "Copy" icon throws the error:

[Violation] Permissions policy violation: The Clipboard API has been blocked because of a permissions policy applied to the current document. See https://crbug.com/414348233 for more details.

i couldn't fully parse the issue, but it seemed to be a CORS-type problem in Chromium browsers. if we wanted to try and fix this, we could add logic to suppress the share tab if

• Atlascope is loaded as an iframe AND
• this browser is Chrome, Brave, Arc

i don't think we necessarily need to change anything, but wanted to document this
