Boundary event associations can be created but can't be loaded

[AndyBan]

Describe the Bug

Associations on bpmn:BoundaryEvents can be modeled, bu won't be rendered on import.

Created:

After load:

Steps to Reproduce

Using https://demo.bpmn.io/new

1. Create Task
2. Add signal boundary event (Happens for other boundary events too)
3. Associate boundary event with data object
4. Export to file, refresh, import from file

Expected Behavior

Associations on Boundary Events will be rendered correctly.

Environment

• Browser: all
• OS: macOS
• Library version: 3, 4, 5

[pinussilvestrus]

Was able to reproduce it on Chrome (for several kinds of Boundary Events). It also appears in older bpmn-js versions (tested under v3).

Changed the issue description to fit our template.

I have tested using npm@5.0.1 and on https://demo.bpmn.io/ and fix doesn't appear to have worked with edge@78 and firefox@68.

Functionality looks to be the same as before where data association isn't displayed. The produced xml looks fine though:

It works perfectly fine to me on yesterday's released version (tag v5.0.1). However, it's not shipped to https://demo.bpmn.io right now.

Oh I do apologize, had a bit of a caching issue and it is indeed working, thanks :)
