[BUG] XL: "Reprint" on single tool gcode does not use the same extruder

[Skinnedknuckles49]

Printer type - Prusa XL dual head factory assembled

Printer firmware version - 4.7.1

Original or Custom firmware - Original

Optional upgrades - stock dual head printer

USB drive or USB/Octoprint - USB drive (Octoprint compatibility is another subject)

Describe the bug Tool 2 was selected and a print completed. On the LCD, I selected "reprint" to just duplicate the last print and E1 started to heat instead of E2 (E2 was still in the tool carriage) and it went through the full pre-print routine heating E1 but moving E2 through cleaning/heat soak/leveling/"printing" while E2 was apparently at room temperature (I didn't check with IR thermometer. Behavior continued after a hard reset to FW 4.7.1.

How to reproduce Simplest and quickest - select Tool 2, then start a print with gcode sliced for a single tool printer and then cancel the print. When offered the option on the LCD select Reprint. Alternatively, let the print complete then select Reprint.

Expected behavior Because Tool 2 is selected and in the carriage, I expect tool 2 to heat up as the print sequence begins on Reprint just as it does on the initial print.

G-code Any gcode sliced for a single tool printer that I've tried has exhibited this behavior.

Crash dump file No crash.

Video Don't have a video but can create one if needed.
