fixrule(meta_viewport_zoomable) to report against (map) only 1.4.4 Resize text and not 1.4.10 Reflow to match ACT

ACT rule b4f0c3: Meta viewport allows for zoom

This rule is implemented by the Checker using the meta_viewport_zoomable:Pass_0,Potential_1 procedure. The implementation is partially consistent with the Meta viewport allows for zoom ACT WCAG 2 rule. The test results were last updated 16 May 2023.

Although it correctly covers all 11 test cases, the Checker mapping reports different success criteria as failed from what is expected by the ACT rule. ACT expects only one SC:
1.4.4 Resize text
while the Checker ruleID meta_viewport_zoomable reports against two SCs:
1.4.4 Resize text
1.4.10 Reflow

rulesets: [{
"id": ["IBM_Accessibility", "WCAG_2_1", "WCAG_2_0"],
"num": ["1.4.4"],
"level": eRulePolicy.RECOMMENDATION,
"toolkitLevel": eToolkitLevel.LEVEL_THREE
},
{
"id": ["IBM_Accessibility", "WCAG_2_1"],
"num": ["1.4.10"],
"level": eRulePolicy.RECOMMENDATION,
"toolkitLevel": eToolkitLevel.LEVEL_THREE
}],
act: [{
"b4f0c3": {
"Pass_0": "pass",
"Potential_1": "fail"
}

This issue is to update the mapping to the same SC's as ACT.

Consider changing the eRulePolicy: RECOMMENDATION to a VIOLATION and keep the Potential_1 reason so it maps to
NEEDS REVIEW when reporting in the Checker
messages: {
"en-US": {
"group": "The 'meta[name=viewport]' should not prevent the browser zooming the content",
"Pass_0": "The 'meta[name=viewport]' does not prevent the browser zooming the content",
"Potential_1": "Confirm the 'meta[name=viewport]' with \"{0}\" can be zoomed by user"
}

Consider if style_viewport_resizable
is a better rule to map to ACT since it checks text resize

messages: {
"en-US": {
"group": "Text must scale up to 200% without loss of content or functionality",
"Pass_0": "Rule Passed",
"Potential_1": "Verify that text sized using viewport units can be resized up to 200%"
}
},
rulesets: [{
id: ["IBM_Accessibility", "WCAG_2_0", "WCAG_2_1"],
num: "1.4.4", // num: [ "2.4.4", "x.y.z" ] also allowed
level: eRulePolicy.VIOLATION,
toolkitLevel: eToolkitLevel.LEVEL_THREE
}],
act: [],

• Does style_viewport_resizable trigger fail for the following ACT b4f0c3: Meta viewport allows for zoom test cases?
  • Failed example 1 no, not failed by style_viewport_resizable.
  • Failed example 2 no, not failed by style_viewport_resizable
  • Failed example 3 no, not failed by style_viewport_resizable
  • Failed example 4 no, not failed by style_viewport_resizable

But Checker ruleID meta_viewport_zoomable does trigger fail for the above test cases.

Removed sprint and release info because this issue has not been triaged yet. Added to the ACT Issue Holder epic.

[shunguoy]

triage: should change the 'potential' to 'failure' to map ACT.

[marcjohlic]

Adding this to the R6.1 Rules epic rather than creating a new R6.1 ACT Issue epic for the two late ACT issues that were pulled in. Leaving the issue holder on these two issues for now as a reminder that they were ACT issues that were pulled in at the end of the release.
