MCPE-36057Expanded/zoomed maps do not show previously-explored area
Expected behavior: when creating a zoomed map, the resulting map will have the original map's explored area already filled in.
Actual behavior: the zoomed map is blank, with only the player's small surrounding bubble filled in.
I believe this is new behavior with 1.5.1 or possibly 1.5.0 because I had a 3/4 map created under 1.4 that I tried to expand last night under 1.5.1 and only now did I notice this behavior.

I think this is WAI and OP is just familiar with Console Edition maps. In Bedrock edition, newly-created maps are at Zoom Level 0 (128x128 blocks). The maximum zoom level is 4 (2048x2048 blocks). You can expand your map by placing it on a crafting table and putting a single piece of paper in each of the surrounding squares. See details in the Wiki: https://minecraft.gamepedia.com/Map#Zoom_out
Note also that in 1.5.1 the expanded map will not include the area you originally explored. It will be a blank (but larger) map. This is a bug I think and I'm off to search the bug reports for it. If I don't find it I will create a new bug and link to it here.
New bug MCPE-36057
Wow, that is bizarre. Possibly related: MCPE-36057. I didn't have a zoom-4 map from pre-Aquatic so I can't test the alignment issue. But zooming a map doesn't work like it used to either. Your picture also shows that issue - you ought to have at least all of the same explored area filled in, even if mis-aligned.
This also appears to reset explored Ocean Explorer maps that were in the area of the zoomed regular map. Here's the sequence of events for me:
1) Buy Ocean Explorer map
2) Travel to the indicated location and explore the area, including completely mapping the location of the ocean monument (did not actually go into the monument however)
2a) A portion of the 3/4 zoom regular map was filled in, of course, as I explored the area
3) Back at base, zoom the 3/4 regular map to 4/4 and lose all explored areas as indicated in the original bug description
4) Pick up the ocean explorer map - all areas are back to "unexplored" colors/textures, like I had never been there
5) Buy a 2nd ocean explorer map from the same villager - it is the exact same map (as expected), and also completely unexplored as though I had never been in the area
It certainly seems that the game is completely "unexploring" areas when you zoom maps. I guess mapmaking/zooming is more closely tied than I expected to whatever data structure holds "explored chunks". The game legit thinks I never explored those areas.
