This bug https://bugs.webkit.org/show_bug.cgi?id=228968 might be related. This is about a flaky crash at fast/forms/search/search-zoom-computed-style-height.html and this also started at around same build (100140)

fast/forms/form-element-geometry.html fast/forms/focus-selection-input.html fast/forms/select/listbox-in-multi-column.html Are also flaky crashing on Windows-EWS. Not showing up on the open source directory: https://results.webkit.org/?suite=layout-tests&suite=layout-tests&suite=layout-tests&test=fast%2Fforms%2Ffocus-selection-input.html&test=fast%2Fforms%2Fselect%2Flistbox-in-multi-column.html&test=fast%2Fforms%2Fform-element-geometry.html Seems like the crash logs indicate that they are related to each other. Builds first started showing crashes: fast/forms/form-element-geometry.html: https://ews-build.webkit.org/#/builders/10/builds/100147 fast/forms/focus-selection-input.html: https://ews-build.webkit.org/#/builders/10/builds/100132 fast/forms/select/listbox-in-multi-column.html: https://ews-build.webkit.org/#/builders/10/builds/100140

More fast tests are showing up as flaky tests on Win EWS: fast/events/mouse-cursor-image-set.html fast/forms/input-button-sizes.html fast/forms/input-placeholder-paint-order-2.html fast/forms/select/select-painting.html fast/forms/textarea/textarea-placeholder-paint-order-2.html It looks like this bug https://bugs.webkit.org/show_bug.cgi?id=228186 is related. Marked expectations to speed up EWS while this bug is being fixed: https://trac.webkit.org/changeset/281236/webkit
