Regressed <img> in <template> or <button> is not loaded properly

Published: | Categories: DOM

Description

Firefox 50 has introduced a regression where images defined within a <template> are not loaded properly when the <img> elements are cloned from the template content and added to somewhere in the active document. An <img> within a <button> is also not loaded due to the same regression. Those failed <img>s will instead show the alternative text if specified. This bug has been fixed with Firefox 50.1.0.
