{Highlighting this since it isn't obvious from this intent: this is a
deprecation
trial for sites that might be broken by the select parser relaxation, and
would like extra time to migrate to the new behavior. The OT will restore
the *old* behavior, while the feature launches in M134 and changes Chrome
to the *new* behavior. }
Contact emailsjar...@chromium.org, mas...@chromium.orgExplainerhttps://open-ui.org/components/customizableselect Specificationhttps://github.com/whatwg/html/pull/10557 Summary This change makes the HTML parser allow additional tags in <select> besides <option>, <optgroup>, and <hr>. This change is in support of the customizable <select> feature but is being shipped first because it can be done separately and has some compat risk which I'd like to get feedback on. This feature is gated by the temporary policy (SelectParserRelaxationEnabled). This is a temporary transition period, and the policy will stop working on milestone M141. Customizable select explainer: https://open-ui.org/components/customizableselect/ I did a compat analysis and determined that the vast majority of sites which would see the effects of the parser changes would not have their behavior changed. More details here: https://github.com/whatwg/html/issues/10310 If there are major issues with this change, I will reassess and make adjustments to the parser as needed. Blink componentBlink>HTML>Parser <https://issues.chromium.org/issues?q=customfield1222907:%22Blink%3EHTML%3EParser%22> TAG reviewhttps://github.com/w3ctag/design-reviews/issues/1007 TAG review statusPending Risks Interoperability and Compatibility I believe there is low interop risk because other vendors are reviewing the proposal in WHATWG and are not objected to changing the parser behavior here. There is a compat risk if websites are relying on the old parser behavior. As I mentioned in the main description, I have done an analysis and based on the websites I have investigated I believe there is low risk. If we encounter issues then I will adjust the parser as needed. *Gecko*: Positive ( https://github.com/mozilla/standards-positions/issues/1086) Positive of experimenting: https://github.com/whatwg/html/issues/10310#issuecomment-2189178702 *WebKit*: No signal ( https://github.com/WebKit/standards-positions/issues/414) *Web developers*: No signals ( https://github.com/mozilla/standards-positions/issues/1086) *Other signals*: WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? None Goals for experimentation Ongoing technical constraints While the OT is going, the old parser behavior will need to be maintained. This isn't a significant maintenance burden.
