Change of employer while a withdrawn petition's reactivation is in process

[Stuck_with_H1B]

Dear Friends,

I need some advice for my situation mentioned here.

Got laid off by my employer back in Aug-17, employer also filed I-797 revoke on the last day of my project and it got approved in 2 days. Then I found a project within 60 days grace period and started working on it through same employer. Employer's attorney told  me that they can reactivate the same petition and I should be good. That I-129 is still pending, now I got another company with a better work and salary and I like to transfer my H1 to this new company. This new company is ready to File H1B transfer in premium. My questions are:

1. First of all, is it possible to transfer my H1B to this new company even when my revoked petition's reactivation is under process?

2. What if this new H1B transfer gets rejected? does it affect my ongoing I-797 activation?

3. What if my ongoing I-797 activation gets rejected before this new company gets my H1B transferred to them? Will I be out of status?

Thanks in advance for you suggestions and answers!
