Activating/placing an object with scanner equipped results in scanner switching to weapon

[FUBAR-BDHR]

I've noticed this happening nearly always especially on Kuva survival missions.  If you have your scanner out and are holding the item to convert the life support as soon as it takes it you switch to primary weapon.  This happens even if you are in the middle of a scan.  It always goes to primary even if you had secondary equipped before picking up the converter.  I've also had this happen in mobile defense when I put the datamas in.
