FrSkyX2/D16 bug: binding an XM receiver won't work anymore since 1.3.3.33 #987

While binding a FrSky XM or XM+ receiver works fine in 1.3.3.20, I can't get a successful bind in 1.3.3.33 or 1.3.4.0.

Steps to repeat:

Flash 1.3.3.33 or 1.3.4.0
Power up the XM while holding the bind button. The LED stays solid red
Press Bind on the transmitter
The LED stays solid red. If binding is successful, it should start blinking.

Equipment used:

FrSky XM ACCST 2.1.2 FCC
Taranis Q X7 on OpenTX 2.3.15
iRangeX IRX4+ with Multiprotocol 1.3.3.33 or 1.3.4.0

I confirm this issue exists even on EU LBT version. I suspect the commit that updated bind sequence to support newer receivers like Archer series broke XM+

commit a41123deb26 "FrSky Archer Bind"

Same issue, bind with older version of the MM firmware, but not with the latest one.. I agree with @rogerq that the point where is broke is on the "FrSky Archer Bind" changes.
