#student_button_text is cut off

I've tried changing the NPC dialogue ui (npc_interact) buttons and noticed that despite setting

"$button_text_size": [ "100%", "default" ],
"$button_text_max_size": [ "100%", "100%" ]

any label that binds #student_button_text from student_buttons_collection is still being cut off.
I also tried creating a custom label, no luck.
When i manually set the "text" property to a string it won't be cut off.

Full example npc_interact_screen.json:

"[email protected]_panel": {
"size": [ "100%", 20 ],
"controls": [
{
"button@common_buttons.light_text_button": {
"$button_type_panel": "npc_interact.student_button_label_panel",
"$pressed_button_name": "button.student_button",
"layer": 4,
"size": [ "100%", "100%" ],
"bindings": [
{ "binding_type": "collection_details", "binding_collection_name": "student_buttons_collection", "binding_collection_prefix": "student_buttons" }
]
}
}
],
"bindings": [
{ "binding_name": "#student_button_visible", "binding_type": "collection", "binding_name_override": "#visible", "binding_collection_name": "student_buttons_collection" }
]
},
"student_button_label": {
"type": "label",
"color": "$text_color",
"text": "#student_button_text",
// "text":"#student_button_text", //stops after ~100px
// "text":"HELLO WORLD HELLO WORLD HELLO WORLD HELLO WORLD HELLO WORLD HELLO WORLD HELLO WORLD HELLO WORLD", //renders fully
"bindings": [
{ "binding_name": "#student_button_text", "binding_type": "collection", "binding_collection_name": "student_buttons_collection" }

]
}
