+Quoting the description from qtwebengine-6.7.0-ninja1.12.patch:
+"""
+Patch status: pending being looked at upstream
+
+Issue[1][2][3] also exist in chromium itself[4], and unclear
+why this started happening only with ninja-1.12.0 at the moment.
+
+Just a quickfix, likely not fully correct and seems there may
+be further unresolved race issues.
