POST not allowed when filtering related content

[reithor]

Tested on Ibexa Experience 3.3.6 (using netgen/tagsbundle 4.0.12):

Error is thrown when filtering related content (use form on https://[host]/admin/tags/admin/tag/[tagid]/content):

Symfony\Component\HttpKernel\Exception\MethodNotAllowedHttpException:
No route found for "POST https://localhost:8000/admin/tags/admin/tag/1/content": Method Not Allowed (Allow: GET)

Simple fix could be :

#bundle/Resources/config/routing/admin/tag.yaml
netgen_tags_admin_tag_related_content:
    path: /{tagId}/content
    controller: eztags.admin.controller.related_content:relatedContentAction
    methods: [GET, POST]
