Submitting form inside Landing Page from Page Builder preview results in doubled submissions.
Prereq.: Use symfony env DEV.
- Create new Landing Page.
- Add Form block.
- Add new form using COTF (e.g. singe line, multi line and button).
- Add a submission from Page Builder preview.
- Go to Forms / form from step 3 / Submissions.
Actual result: Submission is doubled.
Expected result: Each submission is stored once.
Remarks: Does not affect symfony env PROD. Does not affect submitting from frontend (both from LP and directly from form).
