Not hidden "Add branch"

[unsortedhashsets]

Describe the Bug

Hi @lordrip,

Add branch button should be hidden, but in any case, it is possible to use it without any workaround and limitations 🤔

Also all E2E tests:

• 10-branching_actions_from_canvas/branches_from_canvas.cy.js
• 10-branching_actions_from_canvas/nested_branches_from_canvas.cy.js

work without errors 🤔

1. If branches already exist (the tab is blocked but opened by default):
   
   

2. If it is the first branch:
   

Same inside nested branch:

Steps to Reproduce the Bug or Issue

1. Check mentioned e2e tests

or

1. Create: step->choice->step
2. Select choice step
3. Click branches tab
4. Add first branch
5. Click choice step
6. See default state with blocked tab but active button
