I think that it is an issue caused by directly handling file contents in Editor.vue.

After saving, it changes file contents directly like this.file.content = ....
If this change is affected to the code mirror value at the same time, the editor will be working as we expected.
But, If the change is not affected to the code mirror value at the same time(that means it will be afftected on next tick), the erorr case will be reproduced.

I think that is the reason why the error is occured or not occurred when I run the repoduction steps multiple times.
(Also, the script validation does not change the file contents but, the file contents are changing in error case)

After I change like below in Editor.vue, there is no more error case can be reproduced.

// this.file.content = this.$refs.editor.getValue();
this.$refs.editor.codemirror.setValue(this.$refs.editor.getValue());

How often can you reproduce the error?
Can you reproduce the error after changing the code like described upon?
