Bug fixes

TinyMCE 8.7.0 also includes the following bug fix<es>:

CSS custom property names and color values in the style attribute were lowercased when parsed

Previously, the TinyMCE style parser lowercased CSS custom property names (such as --MyColor) and color and background-color values when reading the style attribute. This altered case-sensitive values, including CSS custom properties, template placeholders such as {{FooBar}}, and hex colors such as #AABBCC, so the affected styling sometimes did not render as authored.

In TinyMCE 8.7.0, the style parser preserves the original case of CSS custom property names and color and background-color values. Standard property names are still lowercased, and other processing, such as RGB-to-hex conversion, shorthand merging, and security filtering, is unchanged. Case-sensitive colors and custom properties now stay exactly as authored.
