Multiple legends no longer work starting with v2.25.0

Using plotly.js v2.24.1 displays two legends as expected, while changing to a version >= 2.25.0 will only display legend2

Just poking around with the notebook, and it looks like the legend stops working when I set plotly to 2.24.3, so that may be when the bug was introduced.

Thanks for the report.
This looks like a regression.
