Map does not work for exact addresses

[eugene-shramko]

Preconditions

Magento Version: 2.3.1 (Commerce)
Module Map Version: 1.1.6 (in addition to store locator extension)
Environment: Production mode
Configured provider: Google Maps

Steps to reproduce

1. Go to stores page.
2. Put not exact address related to the list of markers and click "Search".
   For instance, "Midland Highway, Kempton TAS, Australia"
3. Check map behavior.
4. Put exact address related to the list of markers and click "Search".
   For instance, "3121 Midland Highway, Kempton TAS, Australia"
5. Check map behavior.

Expected result

The map is moved to corresponding area and related markers are displayed for both 3 & 5 steps.

Actual result

• The map is moved to corresponding area and related markers are displayed for step 3.
• The map is reset for step 5, all markers are displayed.

It looks like the extension expects to retrieve geometry.bounds for every result from Google Maps API during geocoding. In some cases it is not present, so the map is reset according to the current implementation. Probably geometry.viewport data could be used instead or as a fallback.
