### Steps to Reproduce

If you check the example code [here](https://echarts.apache.org/examples/en/editor.html?c=line-simple&code=PYBwLglsB2AEC8sDeAoWsAeBBDEDOAXMmurGAJ4gCmRA5AMYCGYVA5sAE7m0A0J6AE2aMiAbVoBZGL1i0AKgFcqM2gHUqAlXIAWClQDEOEFQGVmphdFoBdEgF8-6cjnxFUpMpRqyAbowA2Srz8sNCMALbeAERYsD5UXLD-MKywzrh4oRFUsNoJVFGOpGGRclQYYCYU_t7uHrAA7hACYNpEAIwADEUewPEcAGbJDXRgHJZMLMH1sFT-_hAgeK6yAHTrtCF29kV4CRBUhLCiIXUeQmAix-0ArN2wAEwAzPcPDwAsPI_tABxf7U8bv93gB2L4PABsnWsPVIFGodAW0GUWxItjsAG4gA), you can see that a very long y axis long is truncated even though `yAxis.nameTextStyle.overflow` is set.

I believe it's related to [this ticket](https://github.com/apache/echarts/issues/18408).

### Current Behavior

Very long y axis names aren't truncated even though `yAxis.nameTextStyle.overflow` is set.

### Expected Behavior

If `yAxis.nameTextStyle.overflow` is set, the y axis name should be truncated.
