[APM] When creating Trace Explorer links `transaction.id` is replaced when page is loaded

[spong]

We're instrumenting the Security Assistant with APM and linking off to the Trace Explorer UI for any given message that has a transaction/trace id. E.g.

const apmTraceLink =
    message.traceData != null
      ? `${basePath}/app/apm/traces/explorer/waterfall?comparisonEnabled=false&detailTab=timeline&environment=ENVIRONMENT_ALL&kuery=&query=transaction.id:%20${message.traceData.transactionId}&rangeFrom=now-1y/d&rangeTo=now&showCriticalPath=false&traceId=${message.traceData.traceId}&transactionId=${message.traceData.transactionId}&type=kql&waterfallItemId=`
      : undefined; 

I first started by just copying the main URL from the Trace Explorer page and replacing traceId and transactionId ala:

http://localhost:5601/kbn/app/apm/traces/explorer/waterfall?comparisonEnabled=false&detailTab=timeline&environment=ENVIRONMENT_ALL&kuery=&query=&rangeFrom=now-1y/d&rangeTo=now&showCriticalPath=false&traceId=37d559d825f68d3b5251f8e16029c604&transactionId=83c8c2c5f680a65d&type=kql&waterfallItemId=

traceId=37d559d825f68d3b5251f8e16029c604
transactionId=83c8c2c5f680a65d

however I noticed that when navigating to the route both the traceId and transactionId were rewritten:

http://localhost:5601/kbn/app/apm/traces/explorer/waterfall?comparisonEnabled=false&detailTab=timeline&environment=ENVIRONMENT_ALL&kuery=&query=&rangeFrom=now-1y/d&rangeTo=now&showCriticalPath=false&traceId=bedffbd989af4982cd7530794bc32c8c&transactionId=019047f20836c69a&type=kql&waterfallItemId=

traceId=bedffbd989af4982cd7530794bc32c8c
transactionId=019047f20836c69a

I then constructed a link with a kql query param for filtering on transaction.id. While the transactionId param got updated to 4a5ff15270e35400 from of 83c8c2c5f680a65d, it seems the search filter overrides this and gives the correct view:

http://localhost:5601/kbn/app/apm/traces/explorer/waterfall?comparisonEnabled=false&detailTab=timeline&environment=ENVIRONMENT_ALL&kuery=&query=transaction.id:%2083c8c2c5f680a65d&rangeFrom=now-1y/d&rangeTo=now&showCriticalPath=false&traceId=37d559d825f68d3b5251f8e16029c604&transactionId=4a5ff15270e35400&type=kql&waterfallItemId=

traceId=37d559d825f68d3b5251f8e16029c604 (not replaced this time!)
transactionId=4a5ff15270e35400
