Overview ruler becomes redundant

<!-- Do you have a question?

Create a typescript file with 2000-3000+ lines of code/blank lines (the more lines the worse it gets), usually starts at around 1500 lines+. 2. Click to place your cursor in the editor half way down the file somewhere 3. Scroll the page so cursor is at very top of screen 4. Observe overview ruler on right hand side of editor and the 'blip' used to indicate location of the cursor is incorrect (not sure what you call these but I refer to them as blips in this issue)  This has caused me a few problems as its also used for search, error and warning blips. Often it will say the item is in my current view when it's not. The bigger my file the more out of sync it is. I'm guessing there's some arbitrary limit to the height of the box used to indicate what the current view is showing and I can understand that there would need to be some limit as it may be hard to view things correctly the more lines of code you add. I propose a few solutions below, not sure which is best: 1) When you reach a point where you cant reduce the blip height and/or window preview height in ruler then don't show anything - This is the quickest and simplest solution but I believe it's better than showing incorrect data. Maybe need someway to show that its being disabled so users don't report another bug saying its not showing :) 2) Put the scroll bar in its own vertical container without the blips and preview and then show 2 or more vertical rulers to the right of it so as you scroll up and down the preview window will show in one of the vertical rulers…
