TYPO3 Core

I was using the editor with around 4 lines of code visible below my cursor towards the lower border of the t3editor browser-window. Upon entering a dot an auto-completion-suggestion popped up. When I accepted this by pressing Enter the view "jumped" so that the line in which I was currently was editing became the top row in the editor-window. The editor scrolled for some reason. This happened to me several times during writing larger TypoScript-blocks and is quite annoying :-(

(experienced this with TYPO3 6.0; other releases might also be affected)
