Thank you for resolving issue. When are you planning to release those versions?

this is fixed in Media Handler 1.7.0, Handler Commons 1.3.0 (due to some major works some of it's dependencies need to be updated as well).

the stray source end tag was a bug.

the the "sizes" attribute is mandatory in this case is in my point of view technically not correct. i've ehanced the API so it is possible to define a value for it, so you can set it e.g. to "100vw".

the recommended syntax has changed a bit - example:
