Classes missing from endpoints after suspending drawing

[panayotisk]

version: jsplumb 5.8.0
description: After suspending drawing and resuming (as described here) the connection endpoints do not acquire the classes jtk-endpoint-connected and jtk-enpoint-full.
expected behavior: One would expect to have consistent classes to use styling via css.
code sandbox: https://codesandbox.io/s/class-jtk-endpoint-connected-missing-after-suspend-q720if?file=/src/index.js
notes: In the code sandbox the red-blue element endpoints that are drawn during suspended drawing are missing the above classes, while the green-yellow element endpoints are keeping these classes. I haven't tried the behavior of the batch() method.

Any updates regarding this bug? I noticed in the sandbox above that the classes are still missing from the suspended endpoints in 5.13.7
