In general Overleaf seems to have a setup with high resilience to problematic LaTeX sources, so that things work there that would not work elsewhere. It can cause problems of interoperability with other LaTeX systems because the Overleaf users learn to ignore any errors and warnings and write code that works only on Overleaf.
