UI frame rate reading seems to be incorrect

[raymondxie]

I am getting uiFps way too high at around 250 fps range

Here is the debug log:
LOG {
"visibleViewCount": 394,
"viewCount": 3852,
"usedCpu": 88.5999984741211,
"jsFps": 35,
"usedRam": 813.3926620483398,
"uiFps": 245
}

And in the RN Perf Monitor display, it shows UI frame rate around 60 fps, which should mostly be that value.
