> {noformat}
> *Workaround*: call {{display.validateNow();}} before {{display.setFocus();}}
> *Notes*:
> * couldn't reproduce the bug with only one line; we seem to need the text to wrap around
the second line.
> * couldn't reproduce the bug if the span representing the bullet text wasn't set to an
explicit font size (of any value).
> * could reproduce the bug with many random (non-empty) strings for the bullet text, including
one space.
> * could reproduce the bug when I set the fontWeight instead of the fontSize on the bullet
span. It seems that anything that will get the bullet placed into a separate span rather than
merged with the span containing the main text will reproduce the bug.
