jump-by-word (^+right) goes too far when tabs are involved

compare the following press ^+right when cursor is at left edge depending on whether it’s a tab or a space

   word-here
   ^    ^
   |    + tabs stop here
   + spaces stops here

^-right from beginning of the line goes to the wrong place when the line is indented with a tab – it should go to the same position as if the line were indented with spaces

As Murtada-Altarouti stop working on this issue. I want to ask what is expected behaviour on this? Couse now tab works the same as single space. And the code works becouse we normally use 4 spaces. What should happen when we have \t\t in our code editor?
