Bad Cursor motion

Describe the bug

Cursor motion for up and down "k & j" is not correct. If the line above or below has tab characters in it the cursor does not go straight down/up, it go somewhere unpredictable. This prevents the use of the repeat command "." with out first moving horizontally. Really slows down edits related to tab inserting or other repeated inserts/deletes

This works fine in VIM for Visual Studio, but VSCODE is not correct and really, really annoying.
Easy to reproduce.

To Reproduce
Enter something like the code below:

	#2 CpuBusHold = {Dev,Reg}; CPU_NCS = 0;
	#9 CPU_NWE = 0;
	#50 CPU_NWE = 1;
	#8 CPU_NCS = 1;
	@(posedge FpgaClk);	// resycn with cloc

In the above code there are preceding tabs (4 stops) before the "#" symbols. Place the cursor on the first "#", insert a tab character, move down a line and hit the repeat character '.' i.e.

"i(tab)(esc)j."

This has completely different behavior from VIM standalone and VIM for Visual Studio (and from every other VI editor I have ever used).

Expected behavior
Work like every other implementation.

Screenshots
Screen shots don't work for curser motion.

Yes I am on the latest VSCode and VSCodeVIM

Start by reproducing the reported sequence in VSCodeVim with lines containing leading tabs: insert a tab, move with j, and repeat with .; compare the cursor position and edit with Vim. Done means vertical motion and repeat editing match the expected Vim behavior without requiring horizontal movement first.
