Description
Reprex app code:
from shiny import App, render, ui
from htmltools import TagList
app_ui = ui.page_fluid(
ui.h3("Scroll down to upload a file"),
*[TagList(i, ui.br()) for i in range(100)],
"(Clicking on `Browse...` causes the window to scroll back up!)",
ui.input_file("file", "File Input"),
ui.output_text_verbatim("txt"),
)
def server(input, output, session):
@output
@render.text
def txt():
return f"input.file(): `{input.file()}`"
app = App(app_ui, server)

Research direction
Start by running the linked Shinylive app or the Python reprex and reproduce the scroll jump when clicking Browse... on ui.input_file(). Trace the file-input UI behavior from there; done means opening the file chooser no longer scrolls the window to the top.
