bug#61503: 29.0.60; js-ts-mode indent incorrect for multiline strings

[Geoff Jacobsen]

When a multiline (backquote) string is defined in a buffer, with
major-mode js-ts-mode, the indent function incorrectly indents the
contents of the string. It should not alter the contents of the string.

Example:

const a = {
  b: `1
2
3
`};

is incorrectly changed to:

const a = {
  b: `1
  2
  3
`};
