brew doctor output

Your system is ready to brew.

Verification

• I ran brew update and am still able to reproduce my issue.
• I have resolved all warnings from brew doctor and that did not fix my problem.

What were you trying to do (and why)?

I ran brew deps --installed --graph to visualize the dependencies between my installed formulae and casks.

What happened (include all command output)?

As expected, Homebrew opened a browser tab with the dependency graph visualized with Graphviz. However, the node for the cask mactex-no-gui was called #<CaskDependent:0x00007fd8bd2ea7a0> instead of its actual name.

What did you expect to happen?

I expected the node in the dependency graph to be called mactex-no-gui since that's what the cask is called. This issue doesn't occur for brew deps --tree but does occur for brew deps --graph regardless of whether the cask is installed. The issue also occurs for the cask mactex.

Step-by-step reproduction instructions (by running brew commands)

The issue exists for both `mactex` and `mactex-no-gui`:
`brew deps --graph mactex` or `brew deps --graph mactex-no-gui`

If `mactex` or `mactex-no-gui` is already installed, then `brew deps --graph --installed` will also reproduce the issue.
