Strange bug ig

snippet Version	Operating System
v1.1.0	Windows 10

Description

When I have to paste multiple lines of codes from different files in the "Snippet Edit Tab", I have to switch into tabs to get those lines of code, but in "Snippet Edit Tab" it can't hold my previous changes that I made in Snippet tab,
Suppose I have 4 files which are opened in VS code,
I have to take some part of my code from all of the four files,
I go to the first file, copy that code and paste that in "Snippet Edit Section"
after that I go to the second file to copy and paste some part of code after the part where I left in "Snippet Edit Section"
But my last change I made was disappears from "Snippet Edit Section"
That means I have to hit "Save Snippet" each and every time!!

Expected Behavior

It should hold my codes in that "Content" section,
My code should be there even after switching tabs,
Once I've done doing changes in Snippet,
I can simply hit "Save Snippet" to save that.

Actual Behavior

As I said, You can say, It doesn't holding my codes, Once I switch between tabs in VS code, my changes disappears

Steps to Reproduce

1. Open multiple tabs in VS code.
2. Try to add some lines in your Existing Snippet
3. Think that you have to copy and paste multiple lines of codes which are present in different files which you opened in your tabs ( VS code Tabs ),
4. You get your first line of code from the first tab and switched to second tab to get another line of code which you have to paste after that, but when you came back in the "Edit Snippet" section, you notice that the first line of code was not there in the "Edit Snippet's content section"
