Problem description
From phetsims/qa#445
Similar to #264
When the y of a vector is 4>y>-4 and the vector resides within the 1st or 4th quadrants then the angle label and the y component length label overlap.
Steps to reproduce
- Go to Explore 2D screen
- Check the Values and Angle boxes
- Switch to either the 1st or 3rd quadrant component radio buttons
- Place a vector down and position it so that it sits at an angle of 90 degrees or -90 degrees (Although any position in the 1st or 4th quadrant will do)
- Adjust the length of the vector so that it measures 0<y<4 or 0>y>-4

Noting that it can occur in phetsims/qa#446 too
@loganbraywork thanks for reporting.
Over in #93, I believe we decided that things are going to overlap, and there's no clear algorithmic way to avoid that. If the user turns on all of the visual representations, then yes, they can create a visual mess. If there's too much clutter or overlap, they should turn off some of the visual representations. In this case specifically, where the component values and angles are overlapping, the user should turn one of those visuals off if they want to clean things up.
Assigning to @arouinfar to confirm. If my recollection is accurate, feel free to close as "won't fix".
Couldn't have said it better myself @pixelzoom. With all representations on, there's going to be times where overlap is unavoidable. Luckily, the the user can toggle things on/off as need be.
