title: Space Button on textfields , not working Flutter Web
body: <p>We have a web project in flutter and sometimes space button is not working in text form fields.
  After refreshing the page, or after a request to server it works again.
  This situation is causing unstable environment for our users and thus a lot of complaints.
  Is there any official documentation, or solution by flutter for this &quot;sometimes space button cannot be used&quot; problem.
  What we notices that, when this problem occurs, fonts are different than it supposed to be, like it's not loaded.
  It is not browser specific because problem occurs at</p>
