Description

When uploading an SVG it is uploaded as media type File instead of Image or the like.

From the discussion:

this is due to SVG by default not being set as an image file type. In order to preserve backwards compatibility, we currently can't change that (people expecting SVG to be created as a File will suddenly get different behavior.

This seems like a good one to fix for v9, adding svg here and mark it as breaking change: https://github.com/umbraco/Umbraco-CMS/blob/v8/dev/src/Umbraco.Core/Configuration/UmbracoSettings/ContentImagingElement.cs#L17

I'll put this as up for grabs to fix in v9, accepting svg as an image by default.

@nul800sebastiaan hey - I am looking at 'up for grabs' issues, this one appears to be resolved in v9 so not sure if you want to mark this issue as closed now?

Thanks @JamieTownsend84 - with the new media picker this is now handled appropriately in both v8 and v9 👍 Time to close!
