    <thetext>This changeset broke the WPE build for ARM 32-bit:

https://build.webkit.org/#/builders/860/builds/24486

The build error is:

/home/buildbot/worker/WPE-Linux-ARM32-bit-Release-Debian-Stable-Build/build/Source/WebCore/rendering/style/StyleRareInheritedData.cpp:74:15: error: static assertion failed due to requirement &apos;sizeof(WebCore::StyleRareInheritedData) &lt;= sizeof(WebCore::GreaterThanOrSameSizeAsStyleRareInheritedData)&apos;: StyleRareInheritedData should bit pack
   74 | static_assert(sizeof(StyleRareInheritedData) &lt;= sizeof(GreaterThanOrSameSizeAsStyleRareInheritedData), &quot;StyleRareInheritedData should bit pack&quot;);
      |               ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
/home/buildbot/worker/WPE-Linux-ARM32-bit-Release-Debian-Stable-Build/build/Source/WebCore/rendering/style/StyleRareInheritedData.cpp:74:46: note: expression evaluates to &apos;416 &lt;= 408&apos;
   74 | static_assert(sizeof(StyleRareInheritedData) &lt;= sizeof(GreaterThanOrSameSizeAsStyleRareInheritedData), &quot;StyleRareInheritedData should bit pack&quot;);

The issue is that the patch added a new field, deviceScaleFactor, to class StyleRareInheritedData without adding a field of the same size to class GreaterThanOrSameSizeAsStyleRareInheritedData.

I don&apos;t understand why the build error was caught only by the 32-bit build and not the 64-bit though.</thetext>
