Galleries are not parsed when using filter_text()

[Eccenux]

Galleries are not parsed at all and returned as a single text node when using filter_text().

Example code:

page_text = """
[[File:Die "Gardine" in der Drachenhöhle. .24df -1-orig.jpg|thumb|right|File desc]]

<gallery mode=packed>
Plik:Die "Gardine" in der Drachenhöhle. .24df -1-orig.jpg|File desc gallery1
Plik:Demanova Cave of Freedom 19.jpg|File desc gallery2
Plik:CuevasdeTalgua.jpg||File desc gallery3
</gallery> 
"""
page_code: Wikicode = mwparserfromhell.parse(page_text)
for text_node in page_code.filter_text():
	print(f'»{text_node}«')

Result for gallery:

»
Plik:Die "Gardine" in der Drachenhöhle. .24df -1-orig.jpg|File desc gallery1
Plik:Demanova Cave of Freedom 19.jpg|File desc gallery2
Plik:CuevasdeTalgua.jpg||File desc gallery3
«

Yet for a file it is at least split to file and params:

»File:Die "Gardine" in der Drachenhöhle. .24df -1-orig.jpg«
»thumb|right|File desc«

(for me the only text node is »File desc«, but at least please make it consistent)
