[Bug]: removeAttributeQuotes cause WhatsApp to not load open-graph images

[nitin2953]

What happened?

Using the removeAttributeQuotes, Open Graph (og:image) tags' attribute values without quotes prevent WhatsApp from loading preview images

Before minification (works as expected):

<meta property="og:image" content="https://example.com/image.jpg">

After minification with removeAttributeQuotes (breaks WhatsApp preview):

<meta property=og:image content=https://example.com/image.jpg>

I don't think this bug would impact many users, but a warning in the README file would be helpful to inform developers of this potential issue when using removeAttributeQuotes with Open Graph tags.

To me it looks like valid HTML:

Browsers interpret the input like this:

For me it seems this is a bug in WhatsApp. If this is a problem, do not use removeAttributeQuotes.
