…efault themes when rendering a form (emodric)This PR was merged into the 3.4 branch.Discussion----------[Form] [TwigBridge] Added option to disable usage of default themes when rendering a form| Q             | A| ------------- | ---| Branch?       | 3.4| Bug fix?      | no| New feature?  | yes| BC breaks?    | no| Deprecations? | yes| Tests pass?   | yes| Fixed tickets | N/A| License       | MIT| Doc PR        |symfony/symfony-docs#8495This adds a possibility to use `only` keyword in `form_theme` tag to disable usage of globally defined form themes, e.g.`{% form_theme form with ['common.html.twig', 'form/fields.html.twig'] only %}`Otherwise, in order to completely control the rendering of the forms (for example in custom admin interfaces), one would need to use a form theme which has all the possible twig blocks defined to prevent globally defined themes to interfere with the rendering.`only` keyword is already used when including a Twig template to transfer only the variables which are explicitly defined in the `include` tag, so it seemed natural to use it here too.This, of course, means that the user will need to manually `use` all of the templates that are required to render the form, including `form_div_layout.html.twig`This issue is described in details over at Symfony Demo repo:symfony/demo#515TODO:- [x] submit changes to the documentationCommits-------e0681f9 [Form] [TwigBridge] Added option to disable usage of default themes when rendering a form
