Google Map pop up misbehavior on Chrome

UPDATE 12 April 2019: Since August 2018 Google map has given the following false behavior on some Chrome browsers. See discussions for latest status.

When trying to save the location, zoom buttons are missing.


When opening location on own photos, the map and all buttons are missing, and only location is shown.


When opening location on someone else's album the map opens but the location indicator and zoom buttons are missing.


A temporary workaround

All those becomes fixed if the map or page output size becomes changed. If one clicks for example Ctrl-+ to change the page layout size, all gets back to normal. Same thing if the user toggles map to full screen and back.

UPDATES:
The reason and solution probably is the outdated API version number called on the link for Google Maps. One should call v=quarterly instead of some version number. See here: developers.google.com/maps/documentation/javascript/versions

It is tested that clearing cache, history and cookies does not fix this.

It has turned out the bug is very selective. On different computers, both having the exact same Chrome browser version, maps work either just right or the mentioned bug appears.

Reported cases where the bug appears:
- Chrome 68.0.3440.106 (Offizieller Build) (64-Bit), OS Windows 10 Home with build 17134.228, display 1920 * 1080 pixels.
- Chrome 68.0.3440.106 (Official Build) (64-bit), OS Windows 7 Enterprise Version 6.1 (Build 7601: Service Pack1), display 1366 x 768.
- Chrome 68.0.3440.106 (Official Build) (64-bit), OS Windows 10, display 1920x1080.
