Missing space between multiline label inside tooltip

[mrleblanc101]

Expected behavior

Given this label ['Yellow', 'subTitle'].
This will render as 2 seperate lines on the canvas.à
I would expect the tooltip to render as Yellow, subTitle.

Current behavior

But currently, it results in Yellow,subTitle with no space after the comma.

Currently, the workaround is to add the space in the second line label like so:
["Yellow", " subTitle"]
