uespLog addon v2.90: uespLogPerformanceMeter.xml element mismatch

[draeath]

While digging into an unrelated issue with an addon, I noticed this in my interface logs:

Error loading XML[uespLogPerformanceMeter.xml(line 7)]: Error=XML_ERROR_MISMATCHED_ELEMENT ErrorID=14 (0xe) Line number=7: XMLElement name=Controls

There doesn't seem to be a closing tag for the <Controls> tag on line 7. However, inserting one at line 42 (between </OnInitialized> and </TopLevelControl> results in subsequent Lua errors:

Lua Error: Load[uespLogPerformanceMeter.xml(30)]: Invalid element [OnMoveStop].
Lua Error: Load[uespLogPerformanceMeter.xml(30)]: Invalid element [OnInitialized].
Lua Error: Load[uespLogPerformanceMeter.xml(13)] (Control): Illegal virtual control inside non-virtual control.

Putting it instead at 34 (between </Control> and <OnMoveStop>) results in the following instead:

Lua Error: Load[uespLogPerformanceMeter.xml(13)] (Control): Illegal virtual control inside non-virtual control.
Lua Error: /EsoUI/Libraries/Globals/GlobalVars.lua:47: attempt to index a nil value
  stack traceback:

  <Locals> suffix = "Label" </Locals>
  /EsoUI/Ingame/Performance/PerformanceMeter.lua:33: in function 'PerformanceMeters:Initialize'
  <Locals> self = [table:1]{}, control = ud </Locals>

  <Locals> control = ud </Locals>
  UESP_PerformanceMeters_Initialized:3: in function '(main chunk)'

I believe this element mismatch was masking other problems, but I'm not familiar enough (read: at all) with ESO addon development beyond savedvariables.
