QML Editor: imports not properly recognized until file is saved (M300)

Hello,

With latest QtCreator, it seems that from time to time, completion fails to recognize some of the imports, until I change something and save to re-trigger the completion.

I attached an example, where for example GameWindow.qml is located into ./Gui/Widgets folder, which is imported. Funny thing is that GameScene.qml is located on the same folder (./Gui/Widgets) but is recognized.

Not sure what is the source cause.

One comment worth noting is that my qmake project has a root .pro file with:

CONFIG += ordered
TEMPLATE = subdirs
SUBDIRS += ImagePlugin MyApp

Then MyApp/MyApp.pro is very standard:

TEMPLATE = app

QT += qml quick
CONFIG += c++17
CONFIG += qtquickcompiler

SOURCES += [...]
HEADERS += [...]

RESOURCES += qml.qrc

QML files are stored into the qml.qrc file.

Might be similar than https://bugreports.qt.io/browse/QTCREATORBUG-26987 but for QML editor (though the bug mentioned in this ticket happened after I manually relaunched qmake, and I opened the QML file after everything was properly rescanned).

Qt version used in the project is Qt 5.14.1.

Thank you,
Best regards,
Louis
