Safari extension service worker does not wakeup after few days

Question

This only happens on iOS on all of the iPhones.

Safari extension works perfectly fine but after few days of inactivity it just stops. I see that content script still injects js that i want but service worker does not wake up.

Here is code that usually works

in content script i call

// wait for service worker to be ready
    const response = await browser.runtime.sendMessage({
      type: NIGHTLY_SAFARI_WAKE_UP,
      randomNumber: randomNumber
    })

in background service worker i respond

 browser.runtime.onMessage.addListener(function (request, _sender, sendResponse) {
    if (request.type === NIGHTLY_SAFARI_WAKE_UP) {
      sendResponse(`I'm awake! ${request.randomNumber}`)
    }
  })

It works perfectly but after some time sendMessage call starts to respond with undefined and service worker does not work at all.
