Default tooltips not working for geom_polygon() on small plots

[ASmirnov-HORIS]

There are default tooltips that pop up when I use aesthetics. These tooltips do not pop up when geometry is geom_polygon() and my plot is small enough. See the example below:

import numpy as np
import geopandas as gpd
from shapely.geometry import Polygon

from lets_plot import *
LetsPlot.setup_html()

n = 50
r = 1.0
s = .05
phi = np.linspace(0, 2 * np.pi, n + 1)[:-1]
X = r * np.cos(phi)
Y = r * np.sin(phi)
xy = list(zip(X, Y))
geometry = [Polygon([(x - s / 2, y - s / 2), \
                     (x - s / 2, y + s / 2), \
                     (x + s / 2, y + s / 2), \
                     (x + s / 2, y - s / 2)]) \
            for x, y in xy]
gdf = gpd.GeoDataFrame(dict(x=X, y=Y, phi=phi), geometry=geometry)

p1 = ggplot(gdf, aes(x='x', y='y')) + \
    geom_point(aes(color='phi')) + \
    scale_color_gradient(low='red', high='blue') + \
    coord_fixed() + ggtitle('Geometry: geom_point()')
p2 = ggplot() + \
    geom_polygon(aes(fill='phi'), data=gdf) + \
    scale_fill_gradient(low='red', high='blue') + \
    coord_fixed() + ggtitle('Geometry: geom_polygon()')

bunch = GGBunch()
bunch.add_plot(p1, 0, 0, 400, 400)
bunch.add_plot(p1, 400, 50, 300, 300)
bunch.add_plot(p2, 0, 400, 400, 400)
bunch.add_plot(p2, 400, 450, 300, 300)
bunch.show()

There was a restriction on small polygons: area was compared with the constant.
