>+        When WebPageProxy::loadFile() is called, we create a SandboxExtension::Handle for the resource path provided
>+        by the caller and pass it to the WebProcess. WebPage::loadRequest() then calls SandboxExtensionTracker::beginLoad()
>+        to store this handle in m_provisionalSandboxExtension for later consumption.
>+
>+        If a reload is issued before this sandbox extension has been consumed, then the following happens:
>+        1. WebPageProxy::reload() does NOT create a SandboxExtension::Handle because it has already issued one earlier.
>+           maybeInitializeSandboxExtensionHandle() returns early due to m_process->hasAssumedReadAccessToURL(url) check.
>+        2. WebPage::reload() then calls SandboxExtensionTracker::beginLoad() with a null handle, which overwrites the
>+           previous m_provisionalSandboxExtension its needs.
>+        3. The load fails because the WebContent process is missing the sandbox extension.
>+
>+        To address the issue, SandboxExtensionTracker::beginLoad() is updated to only overwrite m_provisionalSandboxExtension
>+        if the new handle is not null. This avoids inadvertently clearing a valid sandbox extension we may need for the load,
>+        since the UIProcess sends us a null handle if it previously sent us a sandbox extension for the path in question.
