Save entered data when clicking after clicking "Back" button

Summary

When entering data into a comment (eg. into comment section), a user can accidentally click on a link in the page causing the browser to re-direct to the new page. Clicking the Back button of the browser will return the user to the original issue. However, the behaviour is inconsistent in regards to the already entered data

Steps to Reproduce

Here are videos demonstrating the behaviour

• chrome.mp4
• firefox.mp4

Expected Results

• As a normal project can retrieve the entered data, Service Desk projects should be able to do the same

Actual Results

• Nothing is saved after clicking Back. All data previously entered will be lost

Workaround

• No known workaround

Suggestion

1. Make Firefox (and all other supported browsers) behave the same and able to retrieve entered data; AND
2. Make Service Desk projects behave the same as well so that browsers can retrieve entered data
   OR
3. Have a pop up which warns users such that entered data will be lost
