Steps to replicate:
- Open VE/Source editor
- Scroll the page
There is an error appearing in the console at this point: Uncaught TypeError: this.getSurface(...).setSurfacePadding is not a function
I noticed something else after this error surfaces which looks pretty serious, not sure whether it's relevant to this error. But mentioning it here just in case:
- After step 2, make some changes after this error appears,
- Go to Save Changes dialog,
- Go to Diff panel by clicking on "Review your changes"
- Click on "Save changes"
- Now click on "Edit source"/"Edit", none of the editor opens.
Also, you wont be able to switch to any other tab from this point, not even Read mode.
