Improperly escaping attributes – leading to errors

I noticed a slew of AMP errors on a client’s site this morning. (Alerted by Search Console). The sidebar had invalid values for attributes. When I looked at the source code in the browser I noticed double quotes around attributes in the sidebar (leading to the invalid values and errors). See screenshot:

So, I took a look at the plugin code in the sidebar.php file. On line 67 if I remove the attribute escape function, esc_attr, the issue goes away. I did not dig any further than that, but it seems like it’s being fed double quote in that data array. Or there are some other escaping issues going on.

Note: I am using the amp theme framework as well.
