Editable should prevent edit but not selection

From mouse.ts,

mind.map.addEventListener('click', e => {
   // if (dragMoveHelper.afterMoving) return
   // e.preventDefault() // can cause <a /> tags don't work
   const target = e.target as any
   if (target.tagName === 'ME-EPD') {
     mind.expandNode((target as Expander).previousSibling)
   } else if (!mind.editable) {
     return
   } else if (isTopic(target)) {
     mind.selectNode(target as Topic, false, e)
   } ...
   
   
    mind.map.addEventListener('dblclick', e => {
   e.preventDefault()
   if (!mind.editable) return
   const target = e.target as HTMLElement
   if (isTopic(target)) {
     mind.beginEdit(target as Topic)
   }
 })

Preventing dblclick makes sense but preventing selection itself does not make sense I think. I have a teacher, student use case where students can't edit a node but should be able to select the node and use focus. I currently cannot do this because setting editable = false is making the mindmap readonly with no interactions. Focus or select or unselect are all passive operations and shouldn't be considered for mind.editable

Does anyone have a suggestion on how I can get selection to work without allowing dblclick?

Start in mouse.ts by reading the click and dblclick handlers and how mind.editable gates their behavior. Verify that a non-editable mind map still allows selecting, focusing, and unselecting nodes while double-click editing remains disabled.
