XCTest: Disable animations on iOS Safari browser

Question

I am working on XCUITest to automate some features in Safari browser in iPhone. Intermittently, I am seeing following logs and automation is stuck.

t =   504.16s         Wait for app to idle
t =   625.29s         App animations complete notification not received, will attempt to continue.
t =   625.30s         Synthesize event
t =   625.67s         Wait for app to idle

All the answers on internet suggest to use UIView.setAnimationsEnabled(false). I tried this solution, but this has not helped much.

My question is: Does UIView.setAnimationsEnabled(false) disable the animations only in apps or will this also be applicable for websites in Safari browser? If not, are there any other workarounds?

Found the answer in Disabling waiting for idle state in UI testing of iOS apps. TestBase is my base class extended from XCTestCase

private func disableWaitForIdle() {
    if !TestBase.swizzledOutIdle {
        let original = class_getInstanceMethod(objc_getClass("XCUIApplicationProcess") as? AnyClass, Selector(("waitForQuiescenceIncludingAnimationsIdle:")))
        let replaced = class_getInstanceMethod(type(of: self), #selector(TestBase.replace))!
        method_exchangeImplementations(original!, replaced)
        TestBase.swizzledOutIdle = true
    }
}

@objc func replace() {
    return
}

Usage:

override func setUp() {
        Self.logger.info("Running test method setup before \(self.name)...")
        disableWaitForIdle()
        super.setUp()
        continueAfterFailure = false
        UIView.setAnimationsEnabled(false)
}
