Merge branch 'develop' into sidv/mergeMaster
* develop:
  chore(deps): update all non-major dependencies
  fix(deps): update all non-major dependencies
  fix: `sourceLinkTemplate` in typedoc
  only call getClasses if the diagram renderer supports it
  fix typo
  merge fix: get classDefs only if diagram is in CLASSDEF_DIAGRAMS
  use lodash isEmpty instead of method defined in utils
  chore: Fix cspell
  fix: Type of DiagramStyleClassDef, general cleanup
  change spec descriptions to active voice (= shorter b/c 'should' isn't needed)
  functions and specs: removeExistingElements
  functions and specs: createUserstyles; minor changes
  functions and specs: createCssStyles, appendDivSvgG,cleanUpSvgCode, putIntoIFrame [for render]
  add MockedD3.ts
  const isSandboxed, isLooseSecurityLevel, fontFamily; a few more CONSTs
  more meaningful var names; move related lines together; const idSelector
  comment the main steps (prepare to break into functions that can be tested)
  render: define const iFrameId, enclosingDivID and _selector to use in function
  specs: encodeEntities, decodeEntities
  render: constants
