Rendering citation in flextable to Word document

Bug description

When rendering a citation in a flextable cell to a Word document, the citation formats, but the hypertext linkage to the reference is not included. The hand icon appears when the ctrl button is pushed and hovered over blue text in the citation, but no linkage. The citation and linkage works fine in text.

Steps to reproduce

---
title: "Flextable Rendering in Word"
format:
  docx:
    number-figures: true
    number-tables: true
    number-sections: true
    toc: false

execute:
  echo: false

bibliography: flextable_render_example.bib
link-citations: true
---

```{r setup}
#| warning: false

library(flextable)
library(ftExtra)
library(tidyr)
library(dplyr)

knitr::opts_chunk$set(cache = TRUE)

```

As shown in @tbl-chum-lh-param by @Tynan1997.

```{r}
#| label: tbl-chum-lh-param
#| tbl-cap: "Summer chum salmon life cycle model parameters"

tb <- tibble(
  Parameter = "Average number of natural spawners",
  `Value(s)` = "2,343.6",
  Source = "@Tynan1997",
  Comment = "Years 2017 - 2021"
) 

  ft <- flextable(tb) |> 
  fontsize(size = 9, part = "all") |>
  width(
    j = c(1:4),
    width = c(2.0, 1.5, 1.5, 1.5)
  ) |> 
  bold(part="header") |> 
  align(align="center", part = "header") |> 
    colformat_md("Source")
  
  ft

```

References

::: {#refs}

Expected behavior

The citation should be rendered just like in text and be hyperlinked to the references.

Actual behavior

The citation renders, but there is no hyperlink.
