[UI/UX] Pressing backspace in Beatmap Listing while scrolled down causes an infinite load

Game behaviour

Bug description

Steps to reproduce:

1. Open Beatmap Listing
2. Type something in the search bar
3. Scroll down until the "Sort by:" bar is no longer visible
4. Press backspace (0:05 mark in the attached video)
5. The game hangs up on an infinite load until the user scrolls back up

Backspace works as intended for the most part (erasing a character), visible in the clip after scrolling up.

Pressing any alphanumeric button in the same scenario causes an automatic scroll up to the top so I assume this slight difference in handling the input event is what causes the issue. (On that note, I discovered that the alphanumerics in the same scenario cause the blinking vertical bar thingy "|" to jump to the beginning of the search field instead of the end, shown in the attached screenshot)

Tangentially related suggestions:

1. The loading animation blocks all mouse input except the scrollwheel, demonstrated in the clip. Would it make sense to allow the user to still use mouse buttons in case of an otherwise unrelated long loading time? Or at least the "jump to top" button which gets blocked as well.
2. Would it be beneficial (and worth the effort implementing) to keep the search bar always visible at the top of the screen?

I believe that I have found the root cause. The OnPressed and OnKeyDown events for BeatmapListingSearchControl don't include an OnPressed handler for KeyBindingPressEvent<PlatformAction> which is where backspace is dispatched.

osu/osu.Game/Overlays/BeatmapListing/BeatmapListingSearchControl.cs

Lines 198 to 206 in 4f649c5

	public override bool OnPressed(KeyBindingPressEvent<GlobalAction> e)
	{
	if (!base.OnPressed(e))
	return false;
	TextChanged?.Invoke();
	return true;
	}
	}

proposed solution is to add the handler for platform action, I am testing this locally to look for side effects before putting up a PR

            public override bool OnPressed(KeyBindingPressEvent<PlatformAction> e)
            {
                if (!base.OnPressed(e))
                    return false;

                TextChanged?.Invoke();
                return true;
            }

edit: I have found OnUserTextAdded and OnUserTextRemoved which should have less side effects (e.g. copy and paste) and are a little cleaner than using PlatformAction
