During mochitest, here are the tests that showed the error(s).
 I print the test start and test end line so that we can see in which the error occurs.

```

Regarding too many tags for a message, I found an issue with tag creation. 
See  Bug 1846336 
tag creation fails from Tags pull down menu due to conflict of existing tag name, but the tag actually is created.

I think if we create 40 tags and try to assign them to a single message, we will overflow X-Mozilla-Keys and I wonder what happens then.

```

Regarding too many tags for a message, I found an issue with tag creation. 
See  Bug 1846336 
tag creation fails from Tags pull down menu due to conflict of existing tag name, but the tag actually is created.

I think if we create 40 tags and try to assign them to a single message, we will overflow X-Mozilla-Keys and I wonder what happens then.
