    <thetext>3x fast tests are a constant crash on IOS Debug
fast/canvas/fallback-content.html 
fast/rendering/render-style-null-optgroup-crash.html
fast/dom/HTMLProgressElement/progress-element-with-child-crash.html

HISTORY:
https://results.webkit.org/?suite=layout-tests&amp;suite=layout-tests&amp;suite=layout-tests&amp;test=fast%2Frendering%2Frender-style-null-optgroup-crash.html&amp;test=fast%2Fdom%2FHTMLProgressElement%2Fprogress-element-with-child-crash.html&amp;test=fast%2Fcanvas%2Ffallback-content.html

REPRODUCTION:
I was able to reproduce with the following on IOS26.2 ToT:

rwt --child-processes=1 --ios-simulator --force --no-retry --exit-after-n-crashes-or-timeouts=1 --iterations 10 &lt;TEST&gt;

I am going to mark expectations as pass fail while this pends investigation.</thetext>
