What are you doing?

#9999 introduced the startsWith and endsWith operators, but they seem to be reversed:

What do you expect to happen?

[Op.startsWith]: 'hat' should be defined as hat%, i.e. the string begins with hat and then has anything afterwards.

[Op.endsWith]: 'hat' should be defined as %hat, i.e. the string begins with anything but ends with hat.

What is actually happening?

startsWith and endWith are the reverse of what I expect. The unit tests for this feature exhibit the same behavior.
