Canvas workpads copied to other spaces with random ids cannot be opened

[legrego]

Kibana version: Tested 7.11.1

Steps to reproduce:

1. Create canvas workpad in one space
2. From Saved Objects Management, copy this workpad to another space, using the default setting to Create new objects with random IDs
3. Navigate to the target space, and attempt to load the workpad

Expected behavior:

The workpad should load.

** Actual behavior:**

The workpad fails to load with a 404 error:

Any additional context:

The copy operation works fine if we preserve the existing saved object id, but this is deprecated behavior.

I noticed that canvas workpads seem to have ids that start with the workpad- prefix. Is this somehow a requirement for workpads?

This is a bug in the router we use. I know I opened an issue at some point but I can't seem to find it now. The issue is that when grabbing params from the route, it tries to guess if it's a number by doing a parseFloat on the param. So if the param is the string 1234-5678 a parseFloat will return the number 1234 and it will try to use that as the value, hence the 404 since that id doesn't actually exist.

We need to switch to probably react-router anyways as this router we are currently using is deprecated.

Thanks @crob611, I appreciate the context. I'll remove the security label then since this seems to be a bug with Canvas, and not a bug with the way we're copying these objects between spaces.
