I am using an iframe to publish an interactive chart from Google Sheets. The iframe will not load on the page until I hover over it with a mouse. (Tested with latest chrome browser on desktop and mobile)
Workaround experiment: I changed the iframe from interactive mode to image and the iframe loads immediately.
iframe frameborder="0" height="371" id="chartframe" scrolling="no" seamless="" src="https://docs.google.com/spreadsheets/d/e/2PACX-1vRUJ3BujnYfrxc4FCgIfcCg58qEtuaaHRtFZ33MaM-tn4nemyxbp4i3usiJdwHPkXqOn9V-RcpqdLQe/pubchart?oid=197457924&format=interactive" width="570"
Expected: Up until a couple a days ago the iframe for the charts in interactive mode would load within a few seconds. This has been the behavior for several years.
Issue: Then with no changes to my side, all interactive iframes for all charts across multiple websites & platforms and from multiple sheets fail to display until I hover over the chart area when using interactive mode.
(HTML snip shown is what worked fine until a couple of days ago.)
