[2.0.28] Technologies with a finite max_level sometimes not displaying correctly

[IsaacOscar]

Consider the Steel Plate Productivity technology, and suppose we haven't research it yet.

• In Vanilla, we have:

  Code: Select all

  data.raw["technology"]["steel-plate-productivity"].max_level == "infinite"
  

  Which gives you:

• Now I want to change it to only have 2 levels (instead of infinite):

  Code: Select all

  data.raw["technology"]["steel-plate-productivity"].max_level = 2
  

  It does not however display correctly:

• In contrast, if I rename the technology to end with a -<number>, it works as expected:
  data.raw["technology"]["steel-plate-productivity"].name = "steel-plate-productivity-1"
  data.raw["technology"]["steel-plate-productivity"].max_level = 2
  data:extend{data.raw["technology"]["steel-plate-productivity"]}
  data.raw["technology"]["steel-plate-productivity"] = nil
  Which displays correctly:

Unfortunately, option #3 is not a good solution for my case, as I want to use it for my mod https://mods.factorio.com/mod/no-infinite-technology, however that will prevent people from later removing the mod from their save (anyone who's researched the renamed technology will loose it).

Note that whether or not the upgrade field is true has no affect on the above, neither does researching the technology (the text above the coloured square changes appropriately, but the coloured square itself doesn't change).
Moreover, technologies that already have a number in their name (e.g. artillery-shell-range-1) do not have this problem (I.e. when setting their max_level to a finite value, they display like #3 above),
