I'm happy to hear, I'm not the only one seeing this. Glad to help!

I haven't tried other mail clients myself, but as the style definition is just redundant to the img attributes, I wouldn't expect any regression by this. But HTML emails are full of miracles ;)

Litmus.com has become quite expensive for render previews, so I looked for alternatives. I found Testi.at, which offers some free tests at least. Unfortunately, I was unable to provide the full MIME structure there and thus could not simulate the CID-referenced image that causes the problem in Apple Mail. When I experimented with an externally hosted image, the result looked good in the provided previews. However, I visually identified another issue: Outlook does not seem to support the 'float' style attribute [1 footnote 1]. In the v2 patch, I implemented a workaround to duplicate the 'float' style using an 'align' img attribute. Previews of the resulting rendering can be found at [2].
