Bug Fixes on text editor (mainly shared code)

Native find on page doesn't work reliably (sometimes shows more occurrences than there actually are, doesn't jump to the place in the code when you hit enter)

• Would be great to implement that properly

Starting typing at all makes the current line jump to the bottom of the screen, which is really frustrating and quite confusing.

• Ideally just keep the scroll position what it is when you start typing.
