URI Normalization issue? (PHP Warning: undefined array key)

Hi Koko support,

I just wanted to report a PHP Warning I noticed while reviewing our debug log. The undefined array key warning appears to concern a page that has a normalized permalink slug. (The normalized URL <https://opensiddur.org/about-this-project/policies/%d7%97%d7%9c%d7%a7-%d7%9e%d7%94%d7%96%d7%9b%d7%95%d7%99%d7%95%d7%aa-%d7%a9%d7%9e%d7%95%d7%a8%d7%95%d7%aa/>, or <https://opensiddur.org/about-this-project/policies/חלק-מהזכויות-שמורות>.)
