Trailing colon after show at statement is parsed without error, but changes behavior by resetting some properties on animation start

MWE

Repro bug - Trailing colon after show at caused property reset.zip

Or just the code below in your script.rpy:

define e = Character('Eileen', color="#c8ffc8")
image eileen = Transform("images/eileen happy.png")

transform t:
    linear 1.0 xpos 0.5

label start:

    "BUG REPRO: trailing colon after show at statement does not cause parse error, but changes behavior: character warps to left before moving"

    show e:
        xpos 0.7

    "Ready to move?"

    # 1. Uncomment this for expected behavior
    # show e at t

    # 2. Uncomment this for odd behavior
    show e at t:

    "Moving!"

    return

Run with line 1. uncommented to see expected behavior.

Run with line 2. uncommented to see odd behavior: character warps to left (apparently due to xpos reset) before moving to target position

Oddly enough, even when I used a colon with actual code below to change sprite xoffset, the xpos seemed to reset as well. So maybe the colon is actually setting up something in all cases, then since there is no code below to set positions, the default values show off?
