+I have disabled JavaScript access to the clipboard in my browser settings and
+have recently experienced frustration with the behavior of github.com in
+continually checking for clipboard support. I have discovered that github.com
+erroneously checks for clipboard support by checking the
+.ICD navigator.clipboard.read
+function,
+without taking into account whether the
+.ICD navigator.clipboard
+object is undefined, which can lead to an infinite loop that spikes CPU usage.
+
+I have found a temporary workaround by defining and injecting the
+.ICD navigator.clipboard
+object myself, creating a dummy object with the read and write functions set
+to zero (or some arbitrary non-function value). This solution effectively stops
+the infinite loop from occurring and tricks the website into thinking that
+clipboard support is disabled.

+(function() {
+/* fix: when sites ask for a clipboard such as github.com

+It's important to note that other users who have not disabled clipboard access
+in their browser settings may not have experienced this issue. However, the
+solution provided may still be helpful for those who have disabled clipboard
+access and are experiencing similar issues with github.com's clipboard support
+check.
