bug: menu component npe

[jacobg]

My app's error monitoring reports the following error callstack:

TypeError Cannot read properties of undefined (reading 'offsetWidth') 
    https://localhost/assets/index-fYpPZuaS.js:1031:14144 x2.contentId.loadAnimation
    https://localhost/assets/index-fYpPZuaS.js:1031:15072 x2.contentId.onWillStart
    https://localhost/assets/index-fYpPZuaS.js:1031:12344 onWillStart
    https://localhost/assets/index-fYpPZuaS.js:1057:2485 x
    https://localhost/assets/index-fYpPZuaS.js:1057:2351 HTMLDocument.L

That corresponds to the following line of code:

ionic-framework/core/src/components/menu/menu.tsx

Line 471 in cd5c27a

const width = this.menuInnerEl!.offsetWidth;

So it seems the code needs to handle the possibility of menuInnerEl being undefined.
