On scaffold forms containing rtf type fields, with all default settings, using Internet Explorer 11, the rtf field "drops" the bottom of the rtf window off the screen such that the Done button cannot be clicked.
In order to replicate this issue on the test instance, can you share the following :
version of Confluence
Scaffolding plugin you're currently using
IE 11 version you're currently using
Can you please share with us the storage format of the page for further instigation?
Open Internet Explorer > Click or tap on the gear icon > Click or tap the About Internet Explorer menu item > The complete version number of IE that you're running can be found next to the word Version:under the big Internet Explorer logo.
