Update category attribute isActive fails with REST, "URL key for specified store already exists."

[Widmayer]

I added a category with the following REST-call:

curl -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' --header 'Authorization: Bearer abcd' -d '{
"category": {
"parentId": 2,
"name": "TestCategory",
"isActive": false
}
}' 'http://0.0.0.0/index.php/rest/default/V1/categories'

When I try to update the attribute "isActive" to true with the same call I get an error:

{
"message": "Could not save category: %1",
"parameters": [
"URL key for specified store already exists."
]
}

When I try to use the PUT method with the following command:
curl -X PUT --header 'Content-Type: application/json' --header 'Accept: application/json' --header 'Authorization: Bearer abcd' -d '{
"category": {
"name": "TestCategory",
"isActive": true
}
}' 'http://0.0.0.0/index.php/rest/default/V1/categories/76'
I get the error:
{
"message": "Could not save category: %1",
"parameters": [
"The value of attribute "is_active" must be set"
]
}

is_active is set, so I think this is a bug.
Any hints how to update a category attribute with REST?
