Qt6 available for developer preview

Is this a known issue when building?

File /usr/bin/qmake
  from install of
     qt6-qtbase-devel-6.7.2+dev1+main.20240929091800.2.ge2b0b69-1.1.1.jolla.aarch64 (qt6obs)
  conflicts with file from package
     qtchooser-26-1.6.3.jolla.aarch64 (@System)

File conflicts happen when two packages attempt to install files with the same name but different contents. If you continue, conflicting files will be replaced losing the previous content.
Continue? [yes/no] (no): no

I added the repo like this:
