Backcourt, Or Not ???

First two situations under 2000-01 should give you guidance.
You can also consult the famous backcourt quiz by BktBallRef.

SITUATION 1: A1 is straddling the division line after catching and possessing a pass from A2. A1 then fumbles the ball, so that the ball lands in A’s frontcourt. A1 then regains possession of the ball (still straddling the division line). RULING: A1, with Team A in control, caused the ball to go from backcourt to frontcourt and was the first player to touch the ball again in the backcourt. Therefore, a backcourt violation shall be called. (9-9 Note)

SITUATION 2: Same situation as above, except A1 begins a dribble immediately upon fumbling the ball and retreats to his/her backcourt to avoid a defender. RULING: During a dribble from backcourt to frontcourt, the ball is in the frontcourt when the ball and both feet of the dribbler touch the court entirely in the frontcourt. Therefore, the play is legal and play continues. COMMENT: The provision of, “both feet and the ball being in the frontcourt” to determine frontcourt status, is only relevant during a dribble from backcourt to frontcourt. (4-4-6)

And the situation in the OP is the opposite direction.
