Feature request: stay on page when changing version #2799
Description
Often when I am reading documentation, I want to change the version of the docs I am looking at.
For example, I am currently reading: https://docs.sciml.ai/ModelingToolkit/stable/basics/MTKLanguage/
When I want to read the dev version of this page, I go to the bottom left and change the version to dev.
Instead of forwarding me to https://docs.sciml.ai/ModelingToolkit/dev/basics/MTKLanguage/, this forwards me to the homepage at https://docs.sciml.ai/ModelingToolkit/dev/.
Ofcourse sometimes that particular page is not available in different versions of the documentation, but in that case we can fall back to the homepage. Can we make it so that, if that page is available, changing the version leads to the page I'm currently viewing?
