Have 600 pages named page001-page600.

Open Special:PrefixIndex/page.

It will display first (I don't know the exact number and I'm lazy to count so say...) 100 results.

On the top right you have link "Next page (page101)".

When you click on it, it used to list pages page101-page200, but now it lists only page101.

Thus there's no way to get the entire list of such prefixed pages if it's longer than one page.
