"Create dictionary item" button does not work with extra tree groups

[Lantzify]

Which Umbraco version are you using?

13.0.0+

Bug summary

When adding a new tree group to the translation section. You can no longer use the button "Create dictionary item"

Specifics

When clicking the "Create dictionary item" button it thorws this error in the console log.
Possibly unhandled rejection: {"errorMsg":"No tree menu url defined for node -1"}

From my limited understanding it seems that this line is the bandit in dictionary.list.controller.js:

var rootNode = appState.getTreeState("currentRootNode").root;

It seems to no be able find the correct node.

I couldn't start the Umbraco project locally, so I tried doing this "hacky" thing from my own controller:

var rootNode = appState.getTreeState("currentRootNode").root.children.find(item => item.name === "Settings").children.find(item => item.name === "Dictionary");

And this displays the menu again.

Steps to reproduce

1. Create a new tree group. (Or install a package that adds a new tree group eg, Translation Manager or Auto Dictionaries.)
2. Go to the translation section
3. Click on the Dictionary folder
4. Click on Create dictionary item button.

Expected result / actual result

Expects to still be able to use the button even when extra tree groups are added. The menu for creating a new dictionary item should display

We really appreciate your patience while we wait for our team to have a look at this but we wanted to let you know that we see this and share with you the plan for what comes next.

• We'll assess whether this issue relates to something that has already been fixed in a later version of the release that it has been raised for.
• If it's a bug, is it related to a release that we are actively supporting or is it related to a release that's in the end-of-life or security-only phase?
• We'll replicate the issue to ensure that the problem is as described.
• We'll decide whether the behavior is an issue or if the behavior is intended.

We wish we could work with everyone directly and assess your issue immediately but we're in the fortunate position of having lots of contributions to work with and only a few humans who are able to do it. We are making progress though and in the meantime, we will keep you in the loop and let you know when we have any questions.
