The issue happens only with an attempt to apply CSS3 (CSS Color Module Level 4) rules for image, HEX 4 or 8 digits. This caused by [CSS Parser Bugs "CSS parser is returning an error for #RGBA and #RRGGBBAA hex color values"|https://sourceforge.net/p/cssparser/bugs/88/]
The workaround for this is to use old CSS rules [ https://developer.mozilla.org/en-US/docs/Web/CSS/background-color ] . |
