Controls whether the new HTML parser behavior for the <select> element is enabled
Last updated August 13, 2025
Deprecated
The HTML parser is being changed to allow additional HTML tags inside the <select> element. This policy allows the old HTML parser behavior to be used until M138.
If this policy is enabled or not set, then the HTML parser will allow additional tags inside the <select> element.
If this policy is disabled, then the HTML parser will restrict which tags can be put inside the <select> element.
