flet: Images no longer displaying on WebView

Description Images from assets are no longer being shown on the WebView when using 0.21.1 >

Code example to reproduce the issue:

import flet as ft

imgsrc='./assets/deaf918056f442f1be15fadf7553cd63.png'


def main(page):
  imgObj=ft.Image(src=imgsrc)
  img = ft.Container(content=ft.Row([imgObj,ft.Text('Image'),]), bgcolor="orange")
  page.add(img)

ft.app(main, assets_dir='assets') 

Describe the results you received: When running the app with; app = ft.app(target=main, assets_dir=‘assets’) then it gathers and displays the assets correctly but when running with app = ft.app(target=main, assets_dir=‘assets’, view=ft.WEB_BROWSER) or app = ft.app(target=main, assets_dir=‘assets’, export_asgi_app=True) then all images are not shown

This was not the case in <= 0.20

Describe the results you expected: Images to be shown as expected
