Original GitHub issue: https://github.com/hoppscotch/hoppscotch/issues/3236

Is there an existing issue for this?

I have searched the existing issues

Current behavior

When I enter a more complex XML body for a request with content type application/xml and I send some requests, after some time the XML body disappears (Body Tab, Raw Request Body) and is no longer displayed.
The body is still available and sent when I send a request but it is no longer displayed.
I can only change it if I clear the body (with the trashcan icon) and then enter it agan

Steps to reproduce

Create a POST request
Go to Body, enter content type application/xml
enter a bigger XML as Raw Request Body
send the request
Save the request
Close the request tab, click around in the UI, open the request again
Go to the Body tab
Raw Request Body is not displayed
Send the request and detect that the body is still available but not displayed

Environment

Production

Version

Self-hosted

I also managed to reproduce the issue with the version that is not self hosted.
Steps to reproduce:

Create a POST request to https://echo.hoppscotch.io with the following body (contains an environment variable)
`
<msg:RequestMessage xmlns:msg="http://www.foo.com/TC57/2011/schema/message" xmlns:m="http://www.foo.com/TC57/CIM-abc#">
msg:Header
msg:Verbcreate</msg:Verb>
msg:NounMeterConfig</msg:Noun>
</msg:Header>
msg:Payload
<m:MeterConfig>
<m:Meter>
<m:mRID><></m:mRID>
<m:amrSystem>METER_AMR_SYSTEM</m:amrSystem>
<m:isVirtual>false</m:isVirtual>
<m:serialNumber>Serial - 10137616</m:serialNumber>
<m:timeZone>Europe/Berlin</m:timeZone>
<m:timeZoneOffset>120</m:timeZoneOffset>
```
 		<m:lifecycle>
 			<m:installationDate>2019-01-01</m:installationDate>
 		</m:lifecycle>
 	</m:Meter>
 	<m:ReadingType>
 		<m:Names>
 			<m:name>0.0.2.4.1.1.12.0.0.0.0.0.0.0.0.3.72.0</m:name>
 			<m:NameType>
 				<m:name>NameType</m:name>
 				<m:NameTypeAuthority>
 					<m:name>NameTypeAuthority</m:name>
 				</m:NameTypeAuthority>
 			</m:NameType>
 		</m:Names>
 	</m:ReadingType>			
 </m:MeterConfig>
```
</msg:Payload>
</msg:RequestMessage>

`

Set the content type of the body to aplication/xml
Add a Pre-Request Script that contains
pw.env.set("Meter", "value");

Save the request as "Untitled" in a new collection with name "a"
Create a second request. The second request is a GET request to https://echo.hoppscotch.io and stored as "Untitled1" in the collection "a"
switch to POST request "Untitled"
send POST request "Untitled"
switch to GET request "Untitled1"
send GET request "Untitled1"
switch to tab Pre-Request Script in GET request "Untitled1"
switch to POST request "Untitled" and tab "Body"
Request Body now is gone!
Send POST request "Untitled". Echo shows received XML, so body is still there but is not displayed.
If Body is deleted with trashcan icon, you can add a new body, but you never see the original body again

I get the same issue. Complex xml bodies create errors in the browser console.

I believe this is causing the xml to disappear

I am also able to reproduce this locally hosted. Anyone have a work around?
