Hi @mumairr, some notes after my tests:

1_ In the widget preview, hover over a Link a link image is too big

hyperlink.mp4

2_ In the widget preview, the scroll down bar is missing

hyperlink_2.mp4

3_ The dimensions of the Embedded link change from preview to widget (Is that correct, @tdipisa?)

Hi @ElenaGallo,

1. Fixed, happened due to css properties applied to each img element inside editor if no image is found in link.
2. Unable to replicate the scrollbar error, i added huge text, embedded link and an error image. Let me know if there are specific steps to reproduce it

@mumairr it only happens for the widget created from a map
