Too many decimal places in legend labs for relplot with hue or size keywords

I ran into this problem with a particular dataset. Calling replot with either hue or size causes extremely long labels in the legend because of what looks like floating point arithmetic in the labeling logic.

Example:

test = pd.DataFrame({
 'foo' :[1,2,3,4,5,6,7],
 'bar' :[4,6,8,3,5,4,6],
    'baz':[0.4, 0.19, 0.35, 0.22, 0.35, 0.31, 0.09]
}
)
sns.relplot(
data=test.head(7),
x='foo',
y='bar',
size='baz')

Is there some way that the legend labels could be rounded or otherwise formatted to prevent this?

Workaround for anyone else who finds themselves looking at this:

plot =sns.relplot(
data=test.head(7),
x='foo',
y='bar',
size='baz')

leg = plot._legend
for t in leg.texts:
    # truncate label text to 4 characters
    t.set_text(t.get_text()[:4])

The specific example at the beginning of this thread now produces the expected result, so if you are having a problem in some other context, you need to provide a reproducible example that demonstrates it.
