Event loop gets stuck awaiting the request after last change or requests-async/http3

[gvbgduh]

I've discovered an interesting behaviour recently.
The matter is that the code below starts getting stuck at awaiting the request since the bump of request-async to 0.5.0 (0.4.1 works well), but the only meaningful change in encode/requests-async#48 is bumping of httpcore/http3 to 0.3.0 (if I'm not mistaken). That's why I decided to open an issue here.

I'm wondering if it could be possible to clarify if I'm missing something.
Happy to provide any assistance with investigation/debugging/fixing.

The code example:

import asyncio
import uvloop
import requests_async

myurls = [
    "https://google.com",
    "https://google.com",
]

async def async_get(url):
    resp = await requests_async.get(url)
    return resp.status_code

async def gather_run():
    tasks = [async_get(x) for x in myurls]
    # Await a coroutine
    result_1 = await tasks[0]
    # Or gather them all
    results = await asyncio.gather(*tasks, return_exceptions=True)
    print(f'Results: {results}')
    return results

uvloop.install()
asyncio.run(gather_run())

Note: it behaves same without uvloop.

Gotcha - that was an HTTP/2 issue in an older version.
I've updated requests-async to depend on the http3 now, which appears to resolve the issue.

Sometime soon I'll start recommending just to use http3.AsyncClient() rather than the requests-async wrapper.

Awesome! Thanks a lot for fast update and it's good to know.
