Periods not inserted after links

[solonovamax]

Periods are not being inserted after links in kdoc.

Example:

/**
 * Enables the
 * [progressive compiler mode](https://kotlinlang.org/docs/whatsnew13.html#progressive-mode)
 * 
 * this is a test
 *
 * @see progressiveMode
 */

Expected:

/**
 * Enables the
 * [progressive compiler mode](https://kotlinlang.org/docs/whatsnew13.html#progressive-mode).
 * 
 * this is a test.
 *
 * @see progressiveMode
 */

Actual:

/**
 * Enables the
 * [progressive compiler mode](https://kotlinlang.org/docs/whatsnew13.html#progressive-mode)
 * 
 * this is a test
 *
 * @see progressiveMode
 */

Additional issue:
it seems for some reason that even if the link is removed, a period is not being inserted at the end of the second line. However, it does work if "This" is capitalized.
