Donation Button blocking text entry in Enfold theme by Kriesi

Right after installing the Donation Button plugin, we noticed we were no longer able to enter or edit text in text fields that are part of theme elements in the Enfold theme from Kreisi (version 3.8.4 latest).

If we press letter keys on the keyboard, no text appears in theme element text fields. Only numbers and the period key (including >, which is shift-period) result in characters being displayed in theme element text fields. Also, we cannot copy/paste any text in theme element text fields. But if we disable the Donation Button plugin, text entry/editing works fine in the Enfold theme elements again.

Donation Button solves a problem for us, so I would love to use it if this might be an issue that could be addressed in a future update. Thank you for a very helpful plugin and for considering this issue!
