Description twifty 2017-06-27 00:43:26 UTC
The editor has a nasty habit of auto scrolling the window so that the cursor is back in view. I have found two methods to reproduce the issue.

1: Code folding
Open a file containing enough lines to be able to scroll. Scroll the cursor out of view, scroll until a code foldable block is available. Toggle the folding by clicking the plus or minus on the left hand side.

90% of the time, the tab will auto scroll the document to bring the cursor back into view.

2: Switching tabs
When the code folding (above) works correctly, Ie. a block was opened/closed and the cursor is not in view; switch to another tab then switch back. Hey presto, the cursor is back in view.
