Do not interrupt background file uploading.

[HT-7]

Describe the bug
If an upload is running in background, switching away from the current tab could cause the upload to be interrupted and the tab could be unloaded.

To Reproduce

• Create an account or log in to a website with a file uploader. In this example, we use archive.org .
• Go to https://archive.org/upload
• Add a few hundred megabytes of files into the uploader.
• Mark the item as a "test item" in the uploader, given that this upload is just for testing purposes.
• Fill in the remaining fields in the uploader.
• Tap on "Create your item". The upload progress bar should now appear.
• Switch away from this tab and browse other sites, or switch to other apps. Though I guess the second is out of control for Kiwi Browser.

Expected behavior
When uploading files in background, the tab that is actively uploading files should not be unloaded from memory so other sites can be browsed without worries that it will be interrupted.

The upload should run and finish in background.

Desktop computers and laptops could do this for decades. Time for smartphones to catch up.

Smartphone (please complete the following information):

• Device: Galaxy A52
• Android Version : Android 12
• Kiwi Browser Version: 118

I haven't tested it yet but I think maybe ScriptCat will help in this case because it can run in the background. Ask the ScriptCat community 😉
