v10.0.3

Bug description

Since I have updated my GLPI instance from v9.5 o v10.0, I noticed that CSS child combinator (>) is not taken in account anymore in mail notification templates. All the other CSS rules are taken in account. For example :

p + p {
  color : green;
}

works.

I verified in Thunderbird development tools to conclude that the CSS child combinator is probably replaced with HTML entity.
