Local file redirect behaviour differs from notebook 6.4.12

[scmmmh]

I've run into a problem with displaying image files in a Markdown cell, when running in nbclassic compared to when running in the notebook 6.4.12 directly. I have a simple notebook file and an image in the same directory:

test.ipynb
image.jpeg

In the notebook file, I have the following markdown (in an appropriate cell):

![not found](image.jpeg)

When running via jupyter notebook, the image is displayed correctly, but when running via jupyter nbclassic, the image is not found. Looking at the network traffic, the difference is that notebook6 is redirecting /notebooks/image.jpeg to /files/image.jpeg, while nbclassic is redirecting /notebooks/image.jpeg to /edit/image.jpeg.
