Issue Summary

With the introduction of the new Labels experience is no longer possible to add multiple labels to a page at once, by copying and pasting a space-separated string of labels.

Raising this a bug as it seems it's a regression.

Steps to Reproduce

1. Create a string with multiple labels in it (for example "test1 test2 test3 test4").
2. Copy that string, paste into the labels box and hit enter.

Expected Results

In the previous Labels experience all the labels would be added to the page, in bulk.

Actual Results

The Labels box doesn't recognize spaces as being separators for different labels and only one label can be inserted at a time. 

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
