当禁用“简化分类创建”时，输入分类的收件电子邮件地址非常困难，因为您输入的每个字母后焦点都会丢失。

这应该能解决问题

> <https://github.com/discourse/discourse/pull/37669>
>
> When \`enable\_simplified\_category\_creation\` is disabled, the email fields in cate…gory settings lose focus after every keystroke, making it impossible to type an email address.
> 
> The legacy category editor wraps all tabs in a FormKit \`\<Form\>\` component. The Form wrapper uses \`{{#each (array @data)}}\` which destroys and recreates the entire component tree when \`@data\` changes identity. Since the controller's \`formData\` getter returns a new object (via \`getProperties\`) every time a model property changes, any two-way binding mutation — including every keystroke in a \`\<TextField\>\` — triggers a full teardown and rebuild of all form elements, destroying the focused input.
> 
> This commit converts the email section inputs (\`email\_in\`, \`email\_in\_allow\_strangers\`, \`mailinglist\_mirror\`) from two-way model bindings to use FormKit's data layer (\`form.set\` / \`transientData\`). Edits to these fields no longer mutate the model, so \`formData\` isn't invalidated and the form is not recreated.
> 
> This commit also passes \`form\` to the \`category-email-in\` and \`category-custom-settings\` plugin outlets on the legacy page, matching what the simplified page already does, so that plugins can adopt FormKit as well.
