Bloom esxporting when film is set to transparent

It would be nice to have the bloom from evee export outside of the shape when the film is set to transparent. As of now it only shows up inside of the shape but not outside. In the picture attached you can clearly see the the effect. 0023.png

Officially .png is not premultiplied by the Alpha. However that means you cannot have any color information in transparent areas. Quite a lot of software just ignores png's rules and writes premultiplied data, possibly Blender should do this as well.

PNG just isn't a suitable format for this effect of luminous and transparent. Just switch to using a format that supports this, like EXR.

I wish that video existed when png was created so we could avoid that (png creators too, check comments)
