I am unable to click on a chart title (e.g. "Chart-Title-1") to rename it when using Firefox browser.
In Chrome it works fine.
Release : 20.4
This is resolved by upgrading to UIM/OC 20.4 CU8. (As of 27 Sept. 2023 this no longer works in CU8 and is resolved in CU9)
The chart title edit pencil is added in 20.4 CU9.
