For me, the eror still persists (maps.wikimedia.org). Exactly at zoom #7 (more or less is OK). However not all Burma is blue anymore. The far north and the south (approximately south from Yangon) are good.

Maybe I am ignorant, but what motivation stands behind the (new) editor (NWE), which must be started/executed from VE mode? If the NWE should be the future replacement of the old wikitext editor, I would expect the same usability as for the old editor (i. e. it should be executable/editable independently of the VE). We can safely presume that a big chunk of the load time is caused by the need to load the page in the VE mode.

I support this request.
