Steps to reproduce

Put this in any markdown text to render on GitLab:

UID | Use if severity | Status
--- | --------------- | ---
9   |                 |
6   | **NIWA**HD      | Enabled
7   | NIW**A**HD      | Enabled
8   | NIW**A**HD      | Enabled
1   | NIW**AHD**      | Enabled

| UID | Use if severity | Status |
| --- | --------------- | --- |
| 9   |                 | |
| 6   | **NIWA**HD      | Enabled |
| 7   | NIW**A**HD      | Enabled |
| 8   | NIW**A**HD      | Enabled |
| 1   | NIW**AHD**      | Enabled |

6	NIWAHD	Enabled
7	NIWAHD	Enabled

What is the current bug behavior?

Renders as this fragment:

<table dir="auto">
<thead>
<tr>
<th>UID</th>
<th>Use if severity</th>
<th>Status</th>
</tr>
</thead>
<tbody>
<tr>
<td>9</td>
<td></td>
<td></td>
</tr>
<tr>
<td>6</td>
<td>
<strong>NIWA</strong>HD</td>
<td>Enabled</td>
</tr>
<tr>
<td>7</td>
<td>NIW*<em>A</em>*HD</td>
<td>Enabled</td>
</tr>
<tr>
<td>8</td>
<td>NIW*<em>A</em>*HD</td>
<td>Enabled</td>
</tr>
<tr>
<td>1</td>
<td>NIW*<em>AHD</em>*</td>
<td>Enabled</td>
</tr>
</tbody>
</table>

What is the expected correct behavior?

Renders as this fragment:

<table dir="auto">
<thead>
<tr>
<th>UID</th>
<th>Use if severity</th>
<th>Status</th>
</tr>
</thead>
<tbody>
<tr>
<td>9</td>
<td></td>
<td></td>
</tr>
<tr>
<td>6</td>
<td>
<strong>NIWA</strong>HD</td>
<td>Enabled</td>
</tr>
<tr>
<td>7</td>
<td>NIW<strong>A</strong>HD</td>
<td>Enabled</td>
</tr>
<tr>
<td>8</td>
<td>NIW<strong>A</strong>HD</td>
<td>Enabled</td>
</tr>
<tr>
<td>1</td>
<td>NIW<strong>AHD</strong></td>
<td>Enabled</td>
</tr>
</tbody>
</table>
