L1FPGATrackProducer fails in special relval with outer tracker inefficiency in CMSSW_12_6_4

What

Taken from cms-sw#41357

From https://its.cern.ch/jira/browse/PDMVRELVALS-148, the setup at https://cms-pdmv.cern.ch/relval/api/relvals/get_cmsdriver/CMSSW_12_6_4__RV148-TTbar_14TeV-00005 results in the following exception:

----- Begin Fatal Exception 08-Apr-2023 19:25:59 CEST-----------------------
An exception of category 'LogicError' occurred while
   [0] Processing  Event run: 1 lumi: 80 event: 15924 stream: 0
   [1] Running path 'L1TrackTrigger_step'
   [2] Calling method for module L1FPGATrackProducer/'l1tTTTracksFromExtendedTrackletEmulation'
Exception Message:
WARNING dphi and/or dphiapprox too large : -0.519923 -0.0301464
----- End Fatal Exception -------------------------------------------------
which appears to be triggered from here:

cmssw/L1Trigger/TrackFindingTracklet/src/MatchProcessor.cc

Lines 530 to 533 in 61b0d3d

 if (std::abs(dphi) > 0.5 * settings_.dphisectorHG() || std::abs(dphiapprox) > 0.5 * settings_.dphisectorHG()) { 
   throw cms::Exception("LogicError") << "WARNING dphi and/or dphiapprox too large : " << dphi << " " << dphiapprox 
                                      << endl; 
 } 

I cannot reproduce the problem by the PSet.py file at this link though I see several (probably?) related warnings coming from here:

cmssw/L1Trigger/TrackFindingTracklet/src/MatchCalculator.cc

Lines 406 to 407 in 371fac8

 edm::LogProblem("Tracklet") << "WARNING dphi and/or dphiapprox too large : " << dphi << " " << dphiapprox 
                             << "dphi " << dphi << " Seed / ISeed " << tracklet->getISeed() << endl;

Recipe to reproduce
