QtWebEngineProcessd.exe crashes

Dear Sir or Madam,

using the demobrowser example, when opening the URL https://www.spotify.com/at/download/other/ and clicking the "Windows" link the QtWebEngineProcess sometimes crashes. The crash does not happen every time but can quite easily be trigger when jumping around back and forth using the back-button and clicking the link.
