sizing_mode breaks GMap alignment

Hi!

I’m using bokeh 0.12.5rc3, Python 3.6.1, Chrome 57.0.2987.110 on Ubuntu 16.10. Using this script:

from __future__ import print_function

from bokeh.util.browser import view
from bokeh.document import Document
from bokeh.embed import file_html
from bokeh.models.glyphs import Patch
from bokeh.models import (
     GMapPlot, Range1d, ColumnDataSource, GMapOptions, WheelZoomTool, PanTool
)
from bokeh.resources import INLINE

from bokeh.sampledata.us_states import data as states

API_KEY = "YOUR API KEY"

map_options = GMapOptions(lat=39.5501, lng=-105.7821, map_type="roadmap", zoom=6)

plot = GMapPlot(x_range=Range1d(), y_range=Range1d(), map_options=map_options,
                api_key=API_KEY, sizing_mode='scale_width', width=300, height=100)

source = ColumnDataSource(data=dict(x=states['CO']["lons"], y=states['CO']["lats"]))

patch = Patch(x="x", y="y", line_color="red", fill_color=None)
plot.add_glyph(source, patch)

doc = Document()
doc.add_root(plot)

plot.add_tools(WheelZoomTool(), PanTool())

filename = "maps.html"
with open(filename, "w") as f:
    f.write(file_html(doc, INLINE, "Google Maps Example"))
view(filename)

At first sight there’s no problem with the map:

but if i do anything that resizes the GMap (like resizing the window, or inspecting an element) the polygon get’s misaligned:

if i return the gmap to its initial width the misalignment seems to dissapear, but just panning the map shows that this ‘re alignment’ it’s a kind of glitch:

Maybe this a corner case of, or it’s related to #2964, but that was closed since there wasn’t any code to reproduce the bug, so i’m opening this one instead. Sorry if this was already reported (i searched but didn’t find any similar)

@syonekura I think we closed this issue by accident, I’m sorry about that. Thanks for the quality bug report. We hope to address a bunch of layout issues in the subsequent 0.12.6 release, so we’ll look to resolve this.

@bryevdv Sure, i’ll be waiting for the next release then
