Column '{colId}' template contains <{tag}>, which is not allowed in a cell template. It was dropped.

Since

1.0.1

What happened

The template used a tag on the forbidden list - script, style, iframe and their relatives. The element and its content are dropped from the compiled template; the rest of the template renders normally.

The fix

Build the content with a component renderer if it genuinely needs one of those elements. A cell template is for text and simple markup.
