QmlLS: Sometimes no automatic suggestion

Steps to reproduce:

• have QC with some Qt6.8+ kit (including a working qmlls)
• create some simple Qt Quick Application from template (shouldn't matter whether compat or standard)
• inside the QML file type

tex 

and wait a sec

Expected result:

• QC displays a couple of suggestions including Text, TextEdit,.. as it is done for using the builtin QML/JS stuff

Current result:

• nothing happens (but explicitly triggering a completion will bring up the expected suggestions)

Note: For other entered stuff this works, e.g. 'mou' will bring up MouseArea, 'rec' shows Rectangle,...
