‘Optimised DOM Output’ experiment breaks plugin

Hi. I have used this plugin before and it’s been great – thanks for making it available and the great work.

However, now that Elementor has added the ‘Optimised DOM Output’ experiment – I have found that when this is enabled, the plugin no longer works for backgrounds on Columns. seems to still the be ok on Sections.

A fix would be great, otherwise I think the performance gain from lazy loading bk images is probably greater than that of the ‘Optimised DOM Output’ output.
