Elementor prints the front page of our website on receipts that used Smart Coupons

## Prerequisites

- [X ] I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
- [ ] The issue still exists against the latest stable version of Elementor.

## Description

As requested by the Elementor support desk, we are posting this issue here...

Elementor hijacks the emailed store receipt and prints the ENTIRE FRONT PAGE of our website on it when someone uses a coupon.
Issue does NOT occur if Elementor is disabled.

## Steps to reproduce

Install the WooCommerce Smart Coupons Plugin by StoreApps v4.0.8, v4.5, v4.7, etc.
Install Elementor or Elementor and Elementor Pro
Make the front page of the website an Elementor page
Create a coupon
Select that a coupon message be added to the emailed receipt and write a coupon message into the text box
Use the coupon
Look at the emailed receipt (Both store copy and customer copy)

## Isolating the problem

- [ ] This bug happens with only Elementor plugin active (and Elementor Pro).
- [ ] This bug happens with a default WordPress theme active.
- [X] I can reproduce this bug consistently using the steps above.

To verify and test this issue we made a clean subdomain install installing only WooCommerce, Elementor and Smart Coupons. 100% repeatable.

The Smart Coupon developers looked into it and found this to be the code you are hijacking:

_Thank you for sharing the steps to replicate the issue. I was able to replicate the issue on my machine.

I've rechecked the code of the Smart Coupons plugin & found that there's only one code which is there add the coupon message in the email, which I suppose that the Elementor plugin is overriding.

The code is:
**apply_filters( 'the_content', $coupon_message )**

Can you please share this code with the Elementor developer team & ask how the Elementor plugin can affect this code. Also, share with them that instead of printing the content of the variable $coupon_message, it's printing the content of the home page created by the Elementor plugin._

## Environment

**This report is from one of our test sites, but the issue also occurred on our live site, where it was first noticed, and on our staging site as well. We setup this site just to test this issue in a clean environment.

ALSO, this test site wasn't setup using the latest versions of everything but the staging site is. We wanted to see if the issue was present in older versions as well as newer versions, it is. So please don't just respond with a suggestion to update to the latest versions as we've done that already and the problem persists.**
