Issue description

When imported audio is playing in Audio Stream Importer, unless the playhead is visible, current playback position is not updated.

Steps to reproduce

• Import audio file into project (tested with >3 minute long .mp3)
• Double-click on imported file in File System tab to open Audio Stream Importer
• Press play in bottom-left corner, notice that current playback position in the bottom-right corner is updating
• Make playhead leave your screen by zooming in and etc., notice that current playback position is no longer updated

Minimal reproduction project (MRP)

N/A

[alessandrofama]

The _current_label doesn't get updated since we return early here:

godot/editor/import/audio_stream_import_settings.cpp

Lines 280 to 283 in 179dfdc

	float ofs_x = (_current - zoom_bar->get_value()) * rect.size.width / zoom_bar->get_page();
	if (ofs_x < 0 || ofs_x >= rect.size.width) {
	return;
	}

Any reason for this or could we set the text of the label before that check?

The label could be set before. The early return is presumably to avoid unnecessary computations if there's nothing to display, but if that prevents changing state for a future display, that's a bug.
