Especially when I am deleting text, the cursor sometimes jumps to some random place within the text.
Also when you mark text with double click, you cannot replace it with other text and if you delete it, instead of replacing it directly, your input is blocked.
It's been like this for quite some time now, but after a recent series of annoyances while posting I decided to ask if this was known.
I use Chrome, no special extensions to mention.
