Keyboard cursor moves randomly.

Bug when entering text in character blocks?
When certain conditions are met, the keyboard cursor is forced to move to the front line.

So far, we've found
1. double pressing the same letter and using arrow keys

ex) ㅇㅇ -> ->.
2. typing a single consonant or vowel and pressing end or home forces it to the front.

If this is a feature, it would be nice to have a way to turn it off.
If it's a bug, it needs to be fixed.
I use the CTRL arrow control for END and HOME a lot, so it's kind of annoying.

I couldn't find a banner for bug reports, so I'm posting this.
