However, they should also set the initial value of displaystyle to true and false respectively. The displaystyle value can also be set via an explicit displaystyle attribute and is reset to false by some elements (like mfrac, scripts, roots etc). When displaystyle=true, the operators marked largeop (either via an explicit attribute or as computed from the operator dictionary) should be drawn larger. When displaystyle=false, the operators marked movablelimits (either via an explicit attribute or as computed from the operator dictionary) should have its under/over limits drawn as sub/sup. See the testcase, where a sum symbol is used (largeop and movablelimits per the operator dictionary).

So I guess we can close this bug. 206790 2013-07-16 09:49:06 -0700 2013-07-16 09:49:06 -0700 testcase displaystyle-movablelimits.html text/html 1027 fred.wang PCFkb2N0eXBlIGh0bWw+CjxodG1sPgogIDxoZWFkPgogICAgPHRpdGxlPnRlc3RjYXNlPC90aXRs ZT4KICAgIDxtZXRhIGNoYXJzZXQ9InV0Zi04Ii8+CiAgPC9oZWFkPgogIDxib2R5PgoKICAgIDx0 YWJsZSBib3JkZXI9IjEiPgogICAgICA8dHI+Cgk8dGg+ZGlzcGxheXN0eWxlPSJ0cnVlIjwvdGg+ Cgk8dGg+ZGlzcGxheXN0eWxlPSJmYWxzZSI8L3RoPgoJPHRoPmRpc3BsYXk9ImJsb2NrIjwvdGg+ Cgk8dGg+ZGlzcGxheXN0eWxlPSJpbmxpbmUiPC90aD4KICAgICAgPC90cj4KICAgICAgPHRyPgoJ PHRkPgoJICA8bWF0aD4KCSAgICA8bXN0eWxlIGRpc3BsYXlzdHlsZT0idHJ1ZSI+CgkgICAgICA8 bXVuZGVyb3Zlcj4KCQk8bW8+4oiRPC9tbz4KCQk8bXRleHQ+dW5kZXI8L210ZXh0PgoJCTxtdGV4 dD5vdmVyPC9tdGV4dD4KCSAgICAgIDwvbXVuZGVyb3Zlcj4KCSAgICA8L21zdHlsZT4KCSAgPC9t YXRoPgoJPC90ZD4KCgk8dGQ+IAoJICA8bWF0aD4KCSAgICA8bXN0eWxlIGRpc3BsYXlzdHlsZT0i ZmFsc2UiPgoJICAgICAgPG11bmRlcm92ZXI+CgkJPG1vPuKIkTwvbW8+CgkJPG10ZXh0PnVuZGVy PC9tdGV4dD4KCQk8bXRleHQ+b3ZlcjwvbXRleHQ+CgkgICAgICA8L211bmRlcm92ZXI+CgkgICAg PC9tc3R5bGU+CgkgIDwvbWF0aD4KCTwvdGQ+CgoJPHRkPgoJICA8bWF0aCBkaXNwbGF5PSJibG9j ayI+CgkgICAgPG11bmRlcm92ZXI+CgkgICAgICA8bW8+4oiRPC9tbz4KCSAgICAgIDxtdGV4dD51 bmRlcjwvbXRleHQ+CgkgICAgICA8bXRleHQ+b3ZlcjwvbXRleHQ+CgkgICAgPC9tdW5kZXJvdmVy PgoJICA8L21hdGg+Cgk8L3RkPgoKCTx0ZD4gCgkgIDxtYXRoIGRpc3BsYXk9ImlubGluZSI+Cgkg ICAgPG11bmRlcm92ZXI+CgkgICAgICA8bW8+4oiRPC9tbz4KCSAgICAgIDxtdGV4dD51bmRlcjwv bXRleHQ+CgkgICAgICA8bXRleHQ+b3ZlcjwvbXRleHQ+CgkgICAgPC9tdW5kZXJvdmVyPgoJICA8 L21hdGg+Cgk8L3RkPgogICAgICA8L3RyPgogICAgPC90YWJsZT4KCiAgPC9ib2R5Pgo8L2h0bWw+ Cg==
