Html sanitizer converts #hex color code to rgba

[amishra1911]

Hello Team,

I am using the sanitize method of HtmlSanitizer to sanitize the html code.
I noticed the #hex code present in style tag got converted to rgba.
Is there any way to prevent this conversion?
e.g-

Unfortunately, there isn't currently. It's the result of AngleSharp's CSS parser which behaves in the same way as browsers.

It is indicated that this would be possible by using a custom formatter: AngleSharp/AngleSharp#132 (comment)

It seems you already use a custom formatter, maybe it would be a rather easy fix. Are you open for PRs ?

[mganss]

Sure, but though we do have StyleFormatter now I believe this particular issue is hard to fix at that level. The easiest fix/workaround in the current version is the one described in #330, assuming you can live with all color values output as hex.

It is a pain, if you sanitize for an html email, it creates rgba which various email clients don't support! I'll have to look at Anglesharp then.

See #330 for a workaround/fix.
