For phetsims/qa#277
The words "Slope is ___" on the Slope screen are smaller on the active line then the saved lines. This is most noticeable when you hit save line and the two overlap. Does not occur on published version.
Steps to reproduce:

1. Set stringTest=double
2. Go to slope screen
3. Hit save line button

They probably have different maxWidth values.

Hmmm... When the sim is first started, the sizes the same, see screenshot below. Then after playing with the sim for awhile, the equation on interactive line becomes smaller. Are you seeing this too @KatieWoe?

[KatieWoe]

Yes. Now that I refresh, I do.

[pixelzoom]

It looks like making a vertical line ("Slope is undefined") is the action that makes the interactive line's label reduce its size.

[KatieWoe]

Looks like. And now that you mention it, something similar happens at that spot on the other two screens as well, but mostly noticeable when at the undefined spot.

[KatieWoe]

And in phetsims/qa#278, now that I know more what to look for

[pixelzoom]

@KatieWoe please verify in master. If it looks OK, then leave this issue open for regression testing in next RC.

[KatieWoe]

looks good in master

[pixelzoom]

Pending regression testing in 1.3.0-rc.2.

[KatieWoe]

Confirmed in both rcs

[KatieWoe]

This error seems to be back in phetsims/qa#286 and phetsims/qa#287.

[pixelzoom]

Bummer. #114 and #117 are intertwined. When I made the recent change for #117 (see #117 (comment)), I did test #114, but apparently not well enough.

[pixelzoom]

@KatieWoe please verify this in master. Check with #117, since they are related.

[KatieWoe]

Doesn't happen in the first screens, but still happens on game screens. @pixelzoom

[pixelzoom]

@KatieWoe please elaborate, I don't understand. Lines in the games are not labeled with equations, so how can this issue be relevant to the game screens?

[KatieWoe]

See explanation #117 (comment)

[pixelzoom]

OK, thanks. So there's nothing wrong with the size of equations used to label lines on the graph, correct?

[KatieWoe]

Didn't seem like it

[pixelzoom]

Pending regression testing in 1.3.0-rc.4.

[KatieWoe]

I did have a quick question for GL though. I noticed that "not a line" change size depending on what happened before it. I think this was known (#117 (comment)) but I wanted to make sure before I oked the issue.

Will also be seen with stringTest=long

[pixelzoom]

Thanks @KatieWoe. What you're showing above is relevant only to #117, not this issue. Displaying "is not a line" is handled separately from equations.

So if you don't find anything else, feel free to close this issue.
