Wrong LP/Asset, LP/Sy price in PendleUniversalOracle when LP and Asset/SY decimals are differs

[rudewalt]

I deployed PendleUniversalOracle on Arbitrum for getting price LP-gUSDC-18Dec2025/gUSDC

The result of method getQuote() of PendleUniversalOracle with parameters inAmount = 1e18, base = 0x18ffB61c6d223bd91ec15acC248bb7e670aBcc48, quote = 0xd3443ee1e91af28e5fb858fbd0d72a63ba8046e0 is 2599930

However the result of method getLpToAssetRate() of PendleOracle contract with parameters market = 0x18ffB61c6d223bd91ec15acC248bb7e670aBcc48, twapDuration = 900 is 2599931255361787785

I think the problem in the scale state variable in constrcutor of :

        uint8 baseDecimals = _getDecimals(base);
        uint8 quoteDecimals = _getDecimals(quote);
        scale = ScaleUtils.calcScale(baseDecimals, quoteDecimals, FEED_DECIMALS);

According to Pendle doc "About unit and decimals" we don't need to operate token decimals when using lpToAssetRate, lpToSyRate.

I think one of possible solution is to ignore base and quote decimals scale = ScaleUtils.calcScale(0, 0, FEED_DECIMALS);
