string.dump(f, true) does not work as expected

[Egor Skriptunoff <egor.skriptunoff@...>]

In Lua 5.3 equal functions are converted to different dumps when strip==true.

local function f(x) return x+1 end
local function g(y) return y+1 end
print(string.dump(f, true) == string.dump(g, true))  --> false on Lua 5.3, true on LuaJIT

If both dumps are load()-ed to exactly the same closures, why these dumps are not equal after stripping debug info?
