jEuclid: how to show bar in formula with subscript

In case of mathml:

<math> 
   <mrow> 
    <mover accent="true"> 
     <mrow> 
      <mi> x </mi> 
      <mo> + </mo> 
      <mi> y </mi> 
      <mo> + </mo> 
      <mi> z </mi> 
     </mrow> 
     <mo>¯</mo> 
    </mover> 
   </mrow> 
</math>

jEuclid shows bar over whole formula: enter image description here and it's ok.

But if I add subscript text:

<math> 
  <msub>
   <mrow> 
    <mover accent="true"> 
     <mrow> 
      <mi> x </mi> 
      <mo> + </mo> 
      <mi> y </mi> 
      <mo> + </mo> 
      <mi> z </mi> 
     </mrow> 
     <mo>¯</mo> 
    </mover> 
   </mrow> 
   <mrow>
   <mtext>v</mtext>
  </mrow>
 </msub>
</math>

jEuclid shows bar above y and in small font size: enter image description here

Is is a jEuclid bug? Is there a workaround solution for this?

Solution

  • I've found a workaround solution - first mrow should be enclosed in mstyle:

    <math>
 <msub>
  <mstyle>
   <mrow>
    <mover accent="true">
     <mrow>
      <mi> x </mi>
      <mo> + </mo>
      <mi> y </mi>
      <mo> + </mo>
      <mi> z </mi>
     </mrow>
     <mo>¯</mo>
    </mover>
   </mrow>
  </mstyle>
  <mrow>
   <mtext>v</mtext>
  </mrow>
 </msub>
</math>

    The equation displays as expected: enter image description here
