SN74LVC1T45: Backdrive when powered off causes chip to turn on and latch output low

Part Number: SN74LVC1T45

Hello,

Our customer is using a SN74LVC1T45 to drive an input to us which we have pulled up through a 49.9K to 3.3V and goes to a FET gate.  They are concerned that our pull-up can back drive their transceiver when they are powered down and cause it to power up and latch the output low.  I don't believe this is a real concern, but I'm trying to get some confirmation of whether this is a concern or not.  Any help is greatly appreciated.
