Default tooltip style is no longer legible on Windows in web and desktop builds #71052
Description
Steps to Reproduce
Flutter version 1.24.x and later break past default tooltip style for Web and Desktop builds.
Expected results
In earlier Flutter versions, tooltips had a default style that looked different from more recent Flutter releases.
For example in Web DartPad based on version '1.23.0-18.1.pre Dart SDK 2.10.4' default tooltips looked like this (still did when this was posted, if DartPad version is upgraded later, it might be broken too when the live link is tried further below):
Actual results
In newer versions, e.g. Channel beta, 1.24.0-10.2.pre or higher the default tooltips style now look like this on Web (and Desktop):
The same breaking default tooltip style change also applies to Web and Desktop builds on channels dev and master.
To illustrate the difference more clearly, here is the older default style on web/desktop and the new default style on web/desktop, side by side:
The broken new style on Web and Desktop uses a default font size that is barely legible. It is a bit difficult to see the rationale of why this new style is preferred over the old one. Perhaps it is a bug?

Summary
The default style for tooltips on Web and Desktop has been broken.
