8301712: [linux] Crash on exit from WebKit 615.1

[kevinrushforth]

Clean backport. Tested in connection with 3 other WebKit fixes in the test-kcr-17.0.7 branch, including a successful CI build. I also verfied that the native WebKit code is identical to mainline jfx after applying all patches (excluding a couple of copyright years).
