Application output filter doesn't display last line

It happens on all QtCreator versions since I remember, also with 14.0.2.

Application output filter doesn't display the last line if the last line contains filtered text.

Example:

• in "Application Output" panel, set "Filter" to "Test"
• run application which outputs two lines "Test 1" and "Test 2" (application doesn't close)
• only first line is visible (untill application outputs another line or you modify the "Filter")
